Can you tell me what version of Windows CE you are running? Also what drivers and components you have in your image?

Thank you,

ggirzon,

I would recommend two things:

1) First if you haven't had the chance to yet, please run through the LoCE Windows CE BSP QuickStart Guide, it is linked below, and verify that this issue still occurs with a simple image built for ActiveSync:

2) My other recommendation is to make sure that you are current on all of your driver updates from Dell. This sounds like it's a hardware interaction issue on the PC side and might have something to do with your USB Hosting driver on your PC.

Regards,

I'll check for updates from DELL..

One more question: when the USB driver is installed, the WCEUSBSH.SYS for the "SHARP USB" is older than what what's already installed:

WCEUSBSH.SYS version 3.7.1.3244 December 06, 2004, 2:07:32 PM
1.01.042000.0 August 05, 2003, 9:20:36 PM

I don't install the later .sys since I also use Activesync with PDA's on the same PC.

Thanks,

Gary

Gary,

You should probably upgrade to the latest version of ActiveSync as well since there are numerous known bug fixes. The current release is at version 3.8.0 and is available to download from Microsoft.

You will want to use the SYS file that is packaged in Logic's USBF Workstation driver as well. I'm not sure how this will change the interaction of your PC and other device though.

Thank you,

I've had this happen more times than I can mention.

I think its a bug in the SHARP USB driver used by activesync. When the "crash" occurs, activesync goes down and will not come back up no matter how much the CE device is disconnected/reconnected. Initially I thought that it was the CE device or the driver, but if the "crash" occurs and you plug the CE device into another system with Activesync, a connection will be established.

On my laptop, the other 2 USB slots are no longer functional for all devices: USB mouse, memory sticks, etc.. Additionally, soft shut downs and restarts (via the start menu) do not work. The system will hang after the "Shutting Down" dialog is displayed. The system must be manually reset to get it going again.

All this leads me to believe that it is a SHARP USB driver issue. It seems like it is in a super tight loop due a deadlock condition of some sort and not even the OS can kill it.

It is easy enough to workaround that I haven't bothered reporting it before, but since the thread is up here I figure I'll add on to it.
