I know of no such problems... actually the only problems I've had are with leaving it on. :-) Obviously if you're trying for optimum battery life, then suspend is handy, but in relation to the Blackberry, you're better off just unplugging it when you don't need it connected.

I took a peek at Ubuntu 7.10 Gutsy's latest kernel, and they patch driver/usb/core/quirks.c with a whole list of devices, the Blackberry being one of them, so it looks like this problem will go away for those folks upgrading early. The upcoming Barry 0.9 will hopefully fix this on Ubuntu 7.04 and Fedora 7 as well. I plan to do more testing, but so far CVS's bcharge is performing admirably on my system.

Bcharge uses a hint from udev to find the right device under /sys, and then searches for the files "level", "autosuspend", and "state" in the following order, writing "on", "-1" or "0", and "0" respectively. This only disables autosuspend for the Blackberry that udev detected was just plugged in. Bcharge can't disable this globally. That requires a reboot. - Chris ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
