[REQ] Kernel with USB Host Enabled - HD2 Android Q&A, Help & Troubleshooting and Genera

To all Devs,
May we request to have USB host enable kernel please?
Thanks.

It's not a software issue. HD2 doesn't support USB Host .

Actually it looks like lack of USB host is a software issue. I read in the Linux development thread that USB host is enabled in the HD2 Ubuntu rom..... What I dont know is whether android in its current state supports USB host. Did I read somewhere that USB host is a feature in the upcoming Android 2.3? I am not sure.

HD2 does support usb host. There are kernels in autobuild system that have usb host enabled.
Once the software is setup, (i know only ubuntu) you need to inject power between hd2 and the hardware you want to connect, because our tiny battery can't handdle the 500ma/5V power output needed for most usb hardware.
Search on ubuntu hd2 wiki, you'll find schematics for power injection cable, and people that have succesfully connected keyboards, mouses, and mass storages.

It's not that it cannot handle the power consumption on its microUSB port, it's because there is no way that it can provide power at all (it is not wired to do that), and that's why you have to provide power for all of your USB gadgets with the Y cable, for which you can find the schematics on the htc-linux wiki.

can this be possible?

Theoretically, HD2 should provide power to USB if is switched to OTG. PMIC that HD2 using it (PM7540) is able to do that.

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...

Mini USB host Controller

Can our mini USB ports be used to connect things like usb flash drives, I know it cannot by default but doesnt the samsung and qualcomm chisets support this? I know windows CE supports it as well.
I don't think the Hermes can host USB. There's a newish protocol called USB on the go that's meant to allow devices to communicate without a host, but nobody seems to use it.
Personally I would be happy with a bluetooth usb host device.
no, tytn doesnt have usb host functionality, this has been answered many times in different posts.

USB Host Problem

Hello,
I use Jungo's WinDriver USB to allow my software to communicate with various digital cameras. It works on every USB host equipped Pocket PC except the X7500, any ideas as to what HTC has done differently with this model? I`ve tested under both the standard WM5 ROM and the 2.19 WM6 ROM with the same results. The driver detects the first attach and detach, but not the subsequent ones. Any ideas would be much appreciated before I FedEx my poor X7500 half way around to world to Jungo..
do you have the 4in1 cable? That has a host mode usb port on it!
No need for funny software. The port on the side (miniusb) is not host, but the one on the 4in1 cable is I beleive.
Kick me anyone if im talking out my bumcrack.
I have the 4 in one cable WinDriver is an SDK that allows user mode software to talk to USB devices without writing full device drivers. In my case, it allows me to develop drivers for Canon and Nikon cameras that Windows CE does not otherwise support.
Please excuse my ignorance here, but does this mean i could plug a external hard drive in and read/write to it?
Thanks in advance
The pilgrim
Yes, I have plugged in USB thumb drives and they are recognized. Power drain is the issue with external USB drives. If you have one with external power input, it should work. I may be testing this shortly. I will repost once I have some deffinitive results.

Not all. Some will work, some will experience compatibility issues, and some will have problems due to power consumption. The best way to find out is test it with the host cable attached and see. If the device doesn't initially work try a few things first....try plugging it in to a power source if it's capable of that, try soft reset while device is plugged in, etc. After trying a few different things, let us know the results and what model you have. Maybe post it to the peripheral compatibility thread. Thanks!
I have bought HTC 4 in 1 CABLE and another 4 in 1 usb from poundland and both work perfectly when you connect external pen drives and mouse.

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

uhm ... very nice impact!
are you know the jtag pins? must be the same like your embedded board.
This is not good...
What is the first HTC device to support USB Host?
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
Is it that big fat thing with a detachable keyboard (can't remember the name )? == Athena
and yes

Usb Host

I'm new in this forum and my english is no the best.
I'm searching for a system to enable usb host on dual. Something have an idea?
not 100% sure about nike but the only htc phone i know off which have usb host is Athena
htc dont connect the usb host connectors of the cpu's (those cpu's which support it that is)
no cure to fix it
Rudegar beat me to it..
no usb host mean that a device is able to connect and use other usb devices such a webcams, external harddisks, mice, keyboards and the likes
yes i now what is usb host, but if is only a problem of connection to cpu we can't study how to make it?I work frequently with electronic and if somebody help me we can try to connet it. The bus of usb are only 2 wire connect it to cpu is very simple if cpu is ready to make it! Somebody have a image of this athena chip and pinout?
