Unidentified USB Device - Windows Mobile Development and Hacking General

I have a htc 7501 running WM6 OS and a USB device.
and I have gotten this usb to serial 2303 driver developed by Prolific.
The driver works fine when the device is inserted.
But if I boot up with the device already inserted, I get the "Unidentified
USB Device" message, and it seems the driver hasn't been called during boot up. If I just ingore the message and click "Cancel". and then I unplug the device and plug it back again. It still works fine.
I am wondering is there everthing I can do to get rid of the error message everytime the ppc boots up??

Did you ever solve this issue?

"Unknown Device"

I'm experiencing a weird problem with an O2 Atom Pure device.. Some weeks ago the device started acting weird: sound suddenly not working anymore.. So, we handed it in at the service center and just a few days back we received the handphone, all clean and working again..
So, back home, we connect the device to the PC to do a sync, and all we get is "USB Device Not Recognized". When checking the Device Manager, the USB device will show as "Unknown Device".. I've tried reinstalling ActiveSync, do a hard reset of the device, soft reset of the device, removing the "Unknown Device", rebooting and then trying again.. All without it doing any good..
Does anyone have any thoughts left? I'm lost.. I thought Atom didnt need any device drivers.. Well, my personal one at least doesnt Thanks in advance!
Ps: other devices are sync'ing fine..
Nobody any idea or suggestions?

make sure you're connected directly to USB and not via a hub, check for latest USB drivers, check your Antivirus is not blocking, download latest version activesync (4.5), check that the com port is available on PC.

Boot Loader Mode=Serial Problem

Hi,
After installing wm6(it's up and running great), i have a problem with Active Sync 4.5 on my XP, it gives me an error "USB device not recognised". So i tried to run installation again, when i put BA in Boot Loader mode it comes up with a message "Serial" at the top of the screen and "v2.08" at the bottom.
I have been reading a few threads and from what i see it should read "USB"
at the top.
I have verified that my cradle and PC are working, i have done a clean XP installation and new Active Sync 4.5 install and i still get the "USB device not recognised" error.
Any ideas on how i could solve this problem.
Thanks
USB problem
Is your cradle plugged directly into a spare usb port. (ie NOT a usb hub) It will NOT work if plugged into a hub.
good luck

Mogul goes into bootloader on reset?

I've got a couple of strange problems with my mogul - anytime I need to reset it, it goes into bootloader (both soft and hard resets). However, If I connect it via USB to my pc, the reset will work.
The second problem is a USB connection to the PC only charges the mogul, the pc doesnt actually recognize it (it doesnt give the windows device connection sound)- so i cant flash it to try and solve the first problem. It also isn't recognized when I plug it into USB while in bootloader mode, I just get the "Unrecognized USB device" error in XP and Vista on two different computers. It might be worth noting that I get the USB device connection sound when i reboot the phone, then the "unrecognized usb device" error, then the disconnect sound as the boot finishes and windows mobile loads. I've tested the cable with other devices and tried multipile cables, so I dont think thats the problem
Any suggestions?
Ok, I got the USB working but nothing will keep it from going into bootloader on reset if it isnt connected to my pc. I've reflashed and hard reset to no avail. no one has any suggestions?
I had this same problem w/ my fiance's mogul... as far as i know there's nothing you can do but take it to sprint and get a replacement... and just as an fyi.... i never modded her phone... it was completely stock!

fastboot issue *SOLVED*

Windows does not recognise my phone is fastboot mode.. I searched the forum for issues and they are different to the issue that I am facing.
The device pops up as Android 1.0, and does not accept the regular windows driver which works otherwise. I get the error code 1 (Device not configured properly) as the error in the device manager..
can someone pls pls help me>>
Uninstall your driver and boot into safemode on your pc. Then plug in your phone and reinstall the drivers. Wait till its done and then unplug your phone from the use cable and boot it into fastboot. Wait till its done and then plug your phone in again. Another dialog box will pop up and install the driver again. Un plug your phone and reboot your computer. It should work now. If not try the step again with the usb drivers posted in the spl 100 110 hardspl post under the development section.
i finally got it to work.. i used this driver!

HELP-Serius issue USB DEVICE NOT RECOGNIZED IN Download Mode

Hi
my phone is running blisspop , cmw touch is installed . when i try to connect my phone to my PC , error message saying USB device not recognized , and saying device is malfunctioned.
i tried everything.
tried my phone with my friends laptop
changed usb cable
tried same usb with my friends G2 which is working fine. so this is not issue with USB cable.
so i tried to flash kdz to get rid of problem, i entered my phone "Download mode" my pc still displaying same error message.
is it hardware related issue?
It could be a hardware problem. I'm going through a similar case (but it's not a hardware issue though). By default you shold turn off the phone, connect the usb to the PC (not the phone) and then Hold Vol+ and Power, Until you see it entered download mode, THEN you plug the USB port to the phone.
install driver
