bug report - awusb sw crash / reboot after inserting usb key

0 votes
Good morning,
in a windows xp sp2 virtual image (on esx server) I had a usb-to serial converter attached to the digibox (es-u-1001-r100 / us232r-100 with fdti chipset), and after plugging in an additional usb key (jet flash 4Gb key) the digibox lost the connection and rebooted.

I got the following crash error log from the event log viewer:

What's the frequency of this issue? In other words, does this issue occur every single time you plug in that key?

Also, after the AnywhereUSB loses the connection and reboots, what happens? In other words, are you then able to interface with that key?

- it happens sporadically, not in a deterministic way
- after this event, I can reconnect to the box and use the key

If you haven't already, try the older v2.40 AnywhereUSB driver. You can download it from our FTP site using the info below. The file name is "40002533_G.exe". You should first uninstall the existing 2.50 version by opening the AnywhereUSB Configuration Utility then click "View / Driver Information / Uninstall" and reboot the VM when prompted. After Windows loads, run the the above .exe file.

Does the issue still occur?

Host name: ftp://ftp1.digi.com
