USB Host: Cabling Requirements - JASJAR, XDA Exec, MDA Pro General

It is pretty exciting, the promise of being able to connect a PDA to a numbe of different USB devices in order to increase disk space etc, but it would seem that the extension to the USB 2.0 standard allowing this requires a cable which if I am not mistaken has a miniUSB B type connector on one end (for the HTC Universal end) and a standard type B connector the other end to connect to the peripheral.
If this is correct does anybody know where they can be obtained? If it's not correct could somebody explain what is needed?
thanks

htc universal usb host driver

Anyone got a wm5/ce5 usb host driver for htc universal (pxa270 intel arm processor)? I'm trying to write one, but if someone could save me the effort, please do? I know it will work, as it does under linux.
USB Host on a universal will be great. Didn't know it works under Linux.
driver for view a universal as a sd writer and reader or a driver for the universal for attach a pendrive to a universal?
drivers for attaching a pendrive.
A USB host driver enables you to hook up USB devices like memory key, keyboard/mouse etc. to the universal. This feature is only available on a few pda models made by toshiba, fujitsu, asus, acer etc.

Correct me if I'm wrong but wouldn't it have to be supported by the hardware? As far as I know the Universal does not have USB host so getting a driver wouldn't be much help...
apparently it works under linux so the hardware must support it
Good question. I need the host driver and then a driver for mass storage (e.g. pen drive, hard driver, etc), HID (for keyboard mouse), etc. The htc universal has a usb host controller built into the arm processor (pxa270). The problem is that it also has a usb device controller build in which takes precedent for the mini usb out, so you can use activesyn. However, with the right bit of code you can reconfigure port 2 to act as a usb host. The other problem is that port 2 doesn't have any power (but that is easy to fix with an external power source from a usb hub or battery [I use a single AA battery, (giving 5 volts at 0.5-1 amp), that lasts for 2 hours]).
hi any success yet with the usb host function? is it possible or just a hoax?
nothing personal it just seems that some ppl like to make fun about this topic and spread hoax!
u have any evidences that it works under linux?
maybe this link is helping you in creating a driver!

Suspect that you will also need the proper USB host cable that is used on the Sharp Zaurus under LINUX to let the Universal know that you want the USB port to work in host mode, they are about £10 & available from here http://www.figlabs.com/catalog/product_info.php/products_id/33
I have the Zaurus & Universal so I know the cable fits but I don't have a driver to test.

The USB host is used by Linux on HTC phones, but not for the external USB connector

I have one for wm2003, I not if it worked in wm05.
Yuo can try it?
any success yet??
Dont think I would want to try a WM2003 driver on a WM5 device.

You can do one backup before installing it.
I have installed it in my Universal and I have not had problems with wm5, but it has not worked with my standar cable
I've had no success with it either.. I have a cable that has the correct connectors.. originally used for connecting a usb pen drive to my lcd picture frame.. but like I said no luck with this RATOC driver.

i think that this cable is not enough, what about a 5v power source for the usb pen drive you'd connect?
your universal couldn't supply that, then you need a usb cable that can connect to a power source aswell.
You need to use a powered USB hub if the slave device requires power, there are one or two hubs that run on batteries so you can still be mobile.
You will need a hub if you plan to use more than 1 USB device at the same time.

In any case, while many devices do use a USB Host or USB Slave chip from a higher level, I believe the Universal talks to its USB as a raw stream device, and therefore can (and does, on occasion) act as a pure Serial communication channel (no discernable protocol beyond 8,n,1) or, therefore, any other type of serial-based channel. Yes, what I am saying is that you could, in fact, hook up a Serial ATA hard disk to an RS232 or USB port directly, so long as the device with the port has low enough level access to the port to absolutely control the data I/O.
The problem you face, however, is that to use the USB port as if the device were the host, you would first need to remove or disable whatever makes it work as the slave. In Windows Mobile that's really not an easy job given the number of different devices and different drivers, some with USB chips, some without... On many devices I can imagine that doing that alone would really bugger up general operation. What happens, for example, to ActiveSync when you suddenly get rid of the port it usually talks to for sync?

Some USB devices have batteries, or have their own power supply You can also get USB cables with an extra (mains or battery) feed wired to the USB's power lines in parallel.
whatever happened to this thread?
allmycrud have you seen the thread from Zeno with USB host drivers?
there is at least one report of it working on a Universal, but I can't get it working on wm6.1... still have hopes though, as all reports suggest that USB host is possible on a uni... can never get verification from anyone though...

USB Host

anyone has tried yet usb host functionality ? I found the drivers of ETEN M600/G500 but not tried yet... processor should be the same so the trinity should support this function.
Thank you for your enquiry, the p3600 was not designed to allow usb memory expansion as such there is no current or planned method to enable what you have requested.
It may be possible to find a 3rd party solution but this would not be supported by ourselves but the solution supplier.
Should you have any other problem, please do not hesitate to call us. Your Local number can be found at http://www.europe.htc.com/support/cs_by_phone.html
Best regards,
HTC Support

Could you share either a link or the file?
Should be this
OK, I'm with Hermes, but anyway... According to the specs, E-Tens have S3C2440 while we have SC32442, but they should be the same. The schematics of the evaluation board (p.6) shows that there are two USB hosts: one from DN0/DP0 pins, the second from DN1/DP1 pins. The latter can also be configured as USB Device... and that's what we have at our MiniUSB connector.
So... if E-Ten uses the first USB Host pins, we're out of luck. If they've implemented it in shared mode, the driver should work. But I have a reason for a doubt: M600/M500 have separate I/O pins for USB host and device, while the connector itself is provided on the cradle. If they made it shared, it would be more easy to implement host/device sharing in the cradle rather than in the device...
A soldering iron may help, but I don't want to loose the warranty yet.
An owner of the Platform Builder may recompile the driver to utilize the shared pins as well. That's a better solution.
If you want to make an adapter for tests, note, that you need to supply +5V from an external power supply (which can be a PC USB port), and that you don't need to cross the pins: DN1 is D- for both host and device, and DP1 is D+ for both. Nothing but connectors and wires should be required.
One more note: a USB Host driver for a shared connector should shut down USB Device driver, something similar that WM5torage does. This also makes me doubt that E-Ten uses shared pins, and that's why I believe that a different driver is required.
But it should be possible!
OK, I've made an adaptor from MiniUSB male (to TyTN), USB A female (for devices), and MiniUSB female for power supply.
In the MiniUSB male I shorted pins 4 and 5. At least this way I can use it for charging from other power supplies, and I think it hould not harm, because pin 4 on GND means USB Host for MiniUSB.
I've installed the above drivers, and also USB Mass Storage drivers (attached).
I have a USB mouse, a card rider (4 slots), an MP3 player, and an RS232 port.
Nothing but MP3 player showed any sign of an activity in all my tests.
The MP3 player shows "MASS CONNECT" on its screen if it detects USB activity. If it does not, it just turns to normal operations, showing that it takes power from USB. It turned to this mode after I installed the attached driver. But I see no a mounted disk on TyTN itself.
So, it works somehow, and I'm almost confident it can be made to work...
Probably I just did something wrong... Who else wants to try?
I must add that installed stuff didn't affect the USB Device from working: ActiveSync connects OK, and WM5torage 1.73 works as before.
Hardwarewise, there are a couple of things to try: disconnect pin 4 from GND at the phone side, disconnect power supply from the phone (providing it only to the attached device), or both...
i'm waiting connectors to try something by myself too. Thanks Lurker0 for all this tips.
thread about usb host from eten users
http://www.eten-users.net/index.php?showtopic=4328&st=0
I ended up with a hard reset Of course I made full backup before the tests.
I've found out that GPRS stopped working. The error messages were like "Modem not found" and "The current call should be finished before data connection" (from memory and ranslated from Russian).
Then I found out that hardware settings for OHCI are wrong:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\OHCI]
"MemBase"=dword:B0900000
"Irq"=dword:0000000B
"UseExistingSettings"=dword:00000000
"MemLen"=dword:00001000
"SysIntr"=dword:00000011
"Order"=dword:00000001
"Index"=dword:00000001
"Dll"="ohci.dll"
"Prefix"="HCD"
"InterfaceType"=dword:00000000
IRQ should be 0x1A (from working registry and also Samsung datasheet), and memory base 0xB5900000.
I've deleted ohci.dll and usbd.dll, then uninstalled that HID driver to no available. I needed a working phone now, and decided to hard reset and restore.
It's strange why IRQ and MemBase were wrong. It may explain why it didn't work. Good I noticed them before tests.
Hey Lurker0
Did you get around to trying it again or was the project abandoned?
Would love to hear how you are going with this if you're still working on it =)
No, I did nothing since that.
HTC Herald compatibility
Does anyone know if the herald can host any USB devices

Mini USB to Serial Cable?

Hey guys!
I've searched and searched for something to allow me to transfer data via a serial cable from my phone to device.
Let me try to explain this.
HTC Wizard
Windows Mobile 6 (Explore 1.1)
I have style tap (palm os emulator)
Software for palm os for a stand alone fuel managment system (msefi.com)
So on my car, I use a serial cable to program and get realtime data.
Now I know they make bluetooth to serial adapters for around 70, but I was wondering if they make a mini usb to serial cable for the Mobile OS.
Anyone have any ideas?
Thanks
Chris
Well, you could theoretically get a USB to serial adapter that has a cable. Then cut the USB connector that goes to the PC off the cable and just splice the miniusb plug onto the end. I don't know about device support though I'm going to guess you would have to at least come up with a driver and the device might not support that type of functionality at all anyways.
Since the Wizard doesn't have a USB Host (aka USB OTG) the short answer is no. Even more importantly, the wizard won't power the serial adapter so the device is a dud to begin with.
The odds that the BT to RS232 connector method will work are far greater than the USB method.

DEV: USB Experts

Ok,
If I were to make up an appropriate USB cable.....
1) Could I get my P3600 to talk to a USB control box that controls a light display which is normally driven by a Windows PC?
2) Is there any API facility in the Windows Mobile OS that allows a programmer to send and receive USB data packets or would I have to hit the PocketPC device hardware and bypass the OS?
3) Is any of the above possible?
Thank you very much
using usb it would not be posible
usb comes in 2 types masters and slaves
htc pda's are slaves they cant init comm with usb devices
much like that you cant connect an usb harddisk with an usb webcam
trinity have usb host...
you can see in samsung -
http://www.samsung.com/global/syste...roduct/2007/7/7/324600sc32442x__schamatic.pdf
in page 6 you have usb connection,
in trinity we have usb device, if you want to have usb host you will have to change the wiring inside the trinity.
for this change you will need to replace R75 from 470K to 15K, disconnect R83 and make a short from R76 to gnd with 15K(ohm), disconnect R82 and connect Vbus to 5V
(all the numbers of the resistors are for the Evaluation Board, in the trinity it will be diffrent numbers/connections)!!!!!
this will NOT work with your pc!!!! (need more modifications but can be done)
only host option!!!
you wont able to charge your trinity!!! (need more modifications but can be done)
but you can make switch like in the PDF
and then you will have usb host.
i have done some work on the sc32442 chip and it worked with usb host
(not the trinity).
no because the cpu have something dont mean that it's map'd out in the pcb of the manufacturers
and doing a hardware mod can kill the device and will 100% surely void the warrenty
and when all the hardware changes are then don then he needs to write a usb driver for wm to support the
hardware he want to talk to if non already exist
htc seem to use an external chip to do the usb stuff which is basic
only Athena and flame support it

Is it that big fat thing with a detachable keyboard (can't remember the name )?
Thanks for the replies.
PS One last question....
Does anyone make an SD or miniSD port based USB controller card?
Thanks again

USB - Wiring for ADB?

Hi folks!
I want to connect an android device (it has usb slots... i can plug there 3g dongles, keyboards, wifi etc) with my computer to try to establish an adb session.
Is that possible like that (usb male - male)? Do i have to solder a custom cable - and how would he wiring be to force the android into "client mode"?
Any help is highly appreciated!

to wiring an usb cable is not so hard. normally you only need to solder the same coloured wire together, red to red, white to white, green to green and black to black. but there are already male to male cable to buy.
www.dx.com/p/ult-unite-ult-1234-usb...lated-data-connection-cable-white-60cm-269067
what does your android device have for an usb? is it micro usb or standard (type a)?
if you have a micro usb port so use an usb data cable, most of the charging cable does have data transfer support.
your computer even needs a driver for your android device to get working the adb.
good luck!
ps. on ytube there a lot vids how to... only search and destroy ( your android)

Hi! Thanks for your help! Its a type A jack on that device just like on the computer. Adbd daemon is on the device running but my windows machine cannot detect an usb device with direct soldered pins (or a bought cable which seems to have the same wiring)
I read about possible collitions when both devices of an usb connection are in host mode and that maybe pullup resistors on the data lines are needed - but i didnt fully understand that part. (Its different to the pin shortening of an usb otg wiring which can be found thousand times on google *G*)
can u describe exactly which cable u have used? and sometime the colors of the cable are not correct e.g. red is not +. those are build by chinese manufactures for cheaps goods. so u have even to measure the cable with a voltmeter.
and describe what happen when u plug the cable in the pc. normally windows is always running as main and android as slave.
as you describe u have an usb a type so i guess your android version is minimum 4.x and is already automatically on host status because you said u can put in a 3g dongle...so u have to go to the android command change from inside. i dont know much about linux programming so have to ask a developer. i only do developing hardwares not softwares, sorry for that.
what is your android device? with a datasheet is it better to solve your problem.
Hi KindsKoPP!
Thanks for your help and interest!
Basically I tested with a 1 to 1 wired cable I soldered by cutting 2 usb cables. I double checked colors (measured their output when connected to the computer) and found them ok. Then I connected them 1 to 1 (red-red, black-black, green-green, white-white).
But no usb device showing up or asking for drivers...
I know that adbd is running on the target device.
I pulled up some info here: http://www.valki.com/2014/12/04/analyse-av7/
I am still hoping that those usb devices who are in a double role (like our phones too with their usb otg host mode and client mode for mtp, adb...) are triggerable externally by using special soldered cables (resistors?) ... like "when resistor xy is on D+ -> go to client mode"?
