Sorry for the delayed commentary. The University's mail system decided to start forwarding my mail elsewhere for a couple of weeks and I just tracked it down!
I've had problems with RH 7.2 kernel 2.4.9-13 and 2.4.9-31 seeing the Logitech 3000 Pro without manual intervention to call pwc.o. I've seen it die, or more precisely, misbehave (no longer able to talk to ituntil reboot... and manual modprobe insertion of pwc) after invoking pwcx.o When you unplug, modprobe apparently unload the driver appropriately, but, again, doesn't reload it when it's plugged back in. I'm having fewer problems on the one RH 7.2 system where I've successfully emplaced 2.4.18, but it's still not really happy autodetecting and autoloading the driver, even though it'll load other Philips cameras appropriately. I have not seen a case of the camera dying (in a physical sense) from being plugged in and accessed by Linux drivers. gerry -- Mihnea-Costin Grigore wrote: >On Mon, 15 Apr 2002, Christopher 'smugg' Rosendahl wrote: > >>Hello! >> >>I have a Logitech Quickcam 3000 Pro, and i have troubles getting my usb ports >>to see that it's connected. >> > >[...snip...] > >>But when i unplug/replug my cam i get nothing. >>Does anyone have a clue why this is happening ? >> > > 1) Try plugging the cam into another computer that is known to work >fine, and preferably uses another OS (yes, _that_ OS), and see if it >works. > 2) My guess would be that point 1) yields negative results, in which >case, the cam is probably broken - for good.

Sure enough, it was dead. Can a USB hub damage a device that's >plugged into it? Maybe with the help of the drivers?
