Please help me get activesync to stop disconnecting

Ok, ive got activesync working fine on one of my pcs but on the other it disconnects after about 3 mins. both have identical software antivirus/firewall-wise the only difference is one has a hardware modem/wireless router(the non-working one) and the other uses a wireless usb hub to connect to the internet.
Ive tried pulling the ethernet cable from the back of the non-working pc to no avail, disabling windows firewall etc but nothing stops it disconnecting after about 3-4 minutes.
Ive tried all the suggestions regarding tcp/ip, they were already correct as were the dhcp ones.
im completely baffled by this
the wmstorage program works for a bit longer but gives the error "the device is unavailable due to an i/o error" after about 5 minutes
anyone have a clue why this is happening?

Odd question to ask. Is your unit set to switch off after 3 mins? Just check if the device is on/off (you can have the backlight off, but you should able to see something on the screen) when the activesync disconnect.

on battery power its set to 2 mins but on external (usb?) its unticked. it works ok on the other pc though thats the thing so i assume its a pc settings issue :wink:

As you plugged into the PC directly (not through a USB Hub)? USB hubs have been known to cause problems.

im using a usb extension cable straight into the usb 2.0 card , the only other device is a printer and the keyboard which share a usb hub on another port.
The cable works fine with other devices ie digital camera/camcorder so its not a faulty cable.
Im using a hub on the pc that works (and its only usb1.1) and it shares with the wireless dongle
One thing i did used to get while transferring data was the avg email scanner popping up while my ipaq (which worked fine) was connected. i disabled the email scanner to see if it helped and rebooted but it was no different

ok-think ive fixed it-the (brand new) usb cable must have been faulty cos i connected the mda cable straight into the pc and it worked :roll:
thanks for all your help :wink:

Athena + using USB host with bespoke USB device (FAT 12)

Hi,
I am attempting to connect a bespoke USB device to the athena.
The bespoke device is recognised as both a mass storage device and keyboard in windows XP.
But when plugged into the Athena, the red charging light turns on. But it doesn't appear in file explorer.
One time (though I havn't been able to reproduce it), a dialog box poped up asking me if I wished to format a device. The bespoke device uses FAT12, does anyone know if Windows mobile even supports FAT12?
Also, is there "add-remove hardware" type funtionality in windows mobile? Should I have to reboot each time or should new hardware be picked up straight away?
Any help would be greatly appreciated.

How is it connected - through the built-in usb port or through the 4-in-1 cable?

I'm using the 4-in-1 cable.
One interesting thing, if I reboot it with it plugged in. It hangs for a little while on the windows mobile splash screen. Then if I press the power button once and then again to turn the screen back on. For a few seconds a "Hard drive" is in explorer.
The bespoke device also is detected as HID device and a number of other USB devices (but using only built in Microsoft drivers) when plugged into a PC (i'm in contact with the hardware vendor to geta concise list). So my other theory is that it hangs trying to find the other drivers (if FAT 12 is supported at all).

Ok, I started wondering when you said the red charge light came on. I was wondering if you were plugging it into the sync/charge port and somehow the device was backfeeding some energy, tricking the device to go into charge mode.
I think you are on the right track. Windows Mobile has few built-in drivers, so the delay probably is due to a search for non-existent drivers. If the manufacturer doesn't have WM drivers, you might try looking at other manufactuers with similar devices that do have WM drivers and try them. Others here have gotten peripherals to work that way.
I just found this page which discusses the file system used by WM. I haven't read the links on that page yet.

XWKI4 (and XXKI3) have killed USB OTG

I upgraded (OTA) to XWKI4 and a couple of days later found that USB Host mode has dissapeared. Anyone know why?
I've done some googling but haven't found a lot about it.
I tried XXKI3 via ODIN and it's the same. The blue overscroll doesn't make up for the omission of major functionality.
Why would samsung remove this? Is it maybe just a bug in the kernel or have they deliberately taken it out for some reason?
I presume I can downgrade in ODIN. Bit of a hassle though. I might have to go down the custom firmware route sooner rather than later.

that appen to me too .no USB OTG ,I have XWKI4 and SiyahKernel 2.1
sorry for my English

move down the notification area and there click to connect to your pc. I guess this was made to optimized battery life, because before this is running on background which consumes battery and only needed if connected to computer via usb.
Hope this help you bro.

Connect to PC != USB On-The-Go / USB Host mode.

I'm running XWKJ3 with Speedmod kernel and USB OTG works fine. For me, the most reliable way of getting it to recognise the device is to plug in the OTG cable WITHOUT the USB memory device connected, then plug the USB memory into the cable. Other sequences sometimes don't work.
So I would give that a try if you're not already doing it that way. If it still doesn't work, you could try flashing Speedmod temporarily, and if still no joy, consider upgrading to KJ3.

What are you after in particular?
If it's USB storage, that still works for me on KJ3, however, the ability to connect things like My DSLR to use D5KController (host mode) have gone, presumably because this feature wasn't introduced until API 11, and Samsung had it in there originally, maybe due to porting parts over for the USB storage, then realised it shouldn't be available and removed it.

Thanks, I've tried that and it works (with mass storage).
Oddly, i'm fairly sure (although not 100%) that plugging in the cable (with no device attached) used to cause a notification (something about USB Host mode activated). It does not do that now.
At least I can access media on a memory stick again, that's good.
Thanks for that.

Usb Host Mode Problem

Let me start this thread by stating that I DID have my Nook Color, booted off an sd card with cm9, working with my usb powered hub connected to a mouse, controller, flash drive, and keyboard. But through a possible hardware error on my part, I cannot get it to work anymore. I'm fairly adept at modifying my Android Devices. I used USB Host Controller and looked through my dmesg logs and the only thing I found of note was it recognized my 7 port hub, but had it suspended. I attempted to enabled/disable USB Host in my Terminal Emulator with commands found in the USB Development Thread but it simply did nothing. Reading logs, etc. is not necessarily a strong suit of mine. So finding what MAY by the problem, has been a bit of a pain the past 2 days. However I will detail my problem below:
Items used:
- 7 - Port USB Powered Hub from Micro Center
- OTG Cables bought from Amazon.
- Nook Color (With various roms. Notably Cm7.2, CM9 (Unsure of nightly version), AOKP Build 40):
- Belkin USB Keyboard and Mouse
- PS3 Controller
- Sandisk 16gb Micro Flash Drive
Apps Used:
- Nook Color Tweaks
- USB Host Viewer
- USB Host Diagnostics
- USB Host Controller
About 3 days ago I decided to set up a station for my tablet as a mini-computer. I had successfully connected a mouse and keyboard (independently of each other) previously but I wanted to go ahead and use my powered usb hub and get a real mini-computer experience on my android tablet. These are the results (All tests include the use of an OTG Cable to connected to either the USB Device or Powered Hub):
Test 1:
Rom: CM 7.2 Kang
1 USB Device Connected: Mouse (Yes), Keyboard (Yes), Flash Drive(No), Game Controller(No) - All enabled via Nook Color Tweaks
Devices Connected to Hub: No
Test 2:
Rom: CM 9
1 USB Device Connected: Mouse (Yes), Keyboard (Yes), Flash Drive(No, I believe it required more than 100mah to power), Game Controller (Yes) - All worked by just Plug N Play.
Devices Connected to Hub: Yes (The Mouse, Keyboard, Flash Drive, and Controller worked simultaneously)
[To Note: Inbetween this test I pulled the OTG-Cable connected to the hub without un-mounting the flash drive first. CM 9 wasn't happy and told me to properly un-mount my sdcard first before pulling the cable. (I bowed to my Android lord and said "okay".)]
Test 3:
Rom: AOKP Build 40
1 USB Device Connected: Mouse (Yes), Keyboard (Yes), Flash Drive(No, I believe it required more than 100mah to power), Game Controller(I have not verified) - All worked by using Nook Color Tweaks. Did not Plug N Play.
Devices Connected to a Hub: No (However it will charged).
Problem:
Looking back at my 'To Note'. Somehow I believe this has caused the problem. Since then USB Host Mode has only worked with a single device NOT connected to the USB Hub. Although my Nook will charge connected to the powered hub with or/without the hub turned on it still will not allow a single device to worked. I've used Nook Color Tweaks with my USB Hub plugged in with both USB Host Mode and VBus External Powered checked (In all 3 roms; AOKP, CM 7, and CM 9) and the only successful attempt made where the HUB and all 4 devices worked were in CM 9 for about a day and a half. Then I pulled the OTG Cable without un-mounting the flash drive, and alas, no-go with the Powered USB Hub.
USB Host Controller tells me I have USB Host Mode enabled (In all 3 roms) yet going to connected devices shows nothing. USB Host Viewer (In all 3 roms) shows nothing connected. And USB Host Diagnostics tells me various things that I'm willing to list here if needed (Host API, Kernel, etc), yet each time the USB Devices connected during the diagnosis, they are not recognized.
Troubleshooting:
- I've plugged my usb powered hub to my computer. It works just fine with each device connected, at once, or together.
- Each device works independently connected to my computer (Keyboard, Mouse, Flash Drive, Game Controller).
- I can still connect a keyboard and mouse independently to my nook with Nook Color Tweaks, but Plug N Play does not work.
- I've attempted both USB Host Mode off of SD Card (CM 9) and EMMC (AOKP Build 40) where Plug N Play only worked with SD Card (CM 9).
- The Kernel for all 3 roms has been 2.6.32.xx or greater (Cm 7.2 used Dalingrin's OC kernel, AOKP Build 40 uses 2.6.32.59, and I'm unsure of CM 9's).
At this point I'm at a loss and I am looking for help. I've done a fair bit of searching (Admittingly too much during work) on these forums. As stated in the beginning of my post, I had it working with all 4 devices in CM 9 booted off my sd-card, since then I've switched my EMMC from CM 7.2 Kangs to AOKP Build 40 (hawt) and successfully used both with a mouse and keyboard. But I cannot get the powered USB HUB to do anything BUT power my Nook Color.
Thank you for your responses and if you need logs, links to the items, apps, or roms used,(forum wouldn't let me post all of them) screenshots from apps, anything, I will respond as quickly and as efficiently as possible.

Have you considered on just reinstalling the whole build over from scratch? I think the USB host is part of the drivers in the kernel layer and that kernel layer might have become corrupted. If you got wifi and audio working on that nook color then the likelihood of having a hardware problem by that definition becomes less of an option, the USB hub is driven by the CPU. So if you got cyanogenmod up and booted, this points to a possible kernel opps. You stated you had it up before. I don't work on kang and AOKP builds so how is the stability of the usb host mode for those builds? Sounds more of a software issue and not some hardware issue. Unless you just like trying to decompile software for a learning experience for yourself. Did you do a hardware hack for your nook as stated in this thread here? http://hackaday.com/2010/02/10/usb-host-mode-for-droid/
Also make sure you disable all of your apps on your device, that is another possible cause, we don't know what type of apps or mods you have made.
Unless you got support to your USB the only way to find the problem is to decompile your whole build through ADB. Logs will not find the problem if its in the kernels. Or are you using ADB through wireless? Check this thread here if you haven't seen this thread yet. There is an app that gives you USB host support already. http://forum.xda-developers.com/showthread.php?t=1468531
UPDATE Aug 31st. 2012. Check thread here on USB host support. http://forum.xda-developers.com/showthread.php?t=1459892
If you want more experience on how android operates, you can start off by building your own cyanogenmod on your computer, the cyanogenMod wiki here shows you how. http://wiki.cyanogenmod.com/wiki/Barnes_&_Noble_Nook_Color:_Compile_CyanogenMod_(Linux)

[Q] USB Mouse and keyboard keep disconnecting

I'm a noob, not sure where else to get help on this site about my problem... I'm using a ASUS Notebook K53E Series laptop computer running Windows 7 Home Premium 64-bit Service Pack 1... I'm using a HDMI to project onto a HD TV I have a USB keyboard and mouse hooked up, both Logitech... The problem I'm having is, both the mouse and keyboard keep disconnecting on me... The mouse will go first' I'll move it from one USB port to the other, and it will work, but then stop working again... The keyboard will just stop working, even if I move it I can't get it to reconnect... I have to shutdown my computer to get everything to start working again, but it will only last about a half hour before they stop working again after the reboot... I've went into the device manager, under Universal Serial Bus controllers > Generic USB Hub > properties > Power Management, and unchecked "Allow the computer to turn off this device to save power... This does not help... I then uninstalled it, and rebooted my computer, still doesn't help... I then tried to system restore, I couldn't because I had no restore points, I have no idea why I didn't... I then look if there was any system updates, there was, but minor updates, I updated them anyways, still no go... I'm only having problems with the USB mouse and keyboard... My laptop touch pad and everything else works fine...:fingers-crossed:

... why are you looking for help here? This isn't a tech support forum, it's a dev&hacking forum. It's also not a Win7 forum... there are better places on the Internet to ask for Win7 support! Asus themselves would be a more logical choice, for example.
You could try checking the Event Logs for any abnormal USB events, but I don't really know. Are there any other mice / keyboards you could try, or could you try the ones you have on another computer? Does it work at all to just unplug the mouse/keyboard and plug it in again? Do the devices lose power (lights go out) or do they simply stop responding correctly? Do other USB devices (phone, camera, webcam, headset, flashdrive, whatever) keep on working if you leave them plugged in for a while?

Sorry, like I said I'm a noob... The reason I asked here, because I thought it was a general question for windows OS... I do understand its windows 8 tho... I also didn't want to join some random site to get my answer... I also checked event logs, but I'm not sure how to use it... I have no other computers or mice/ keyboards to test with... The lights stay on, like their still connected, but they don't work... I've pulled them out, and plugged them back in, and even put them in other USB ports... But they will only work for a short while after moving them to a new USB port... They will no longer work in the same port after they stop working until I reboot... I'm also not sure if it's ASUS or Logitech thats the problem...
