Hello all, I'm having problems with a sn9c102 webcam.
- it works when directly attached to the PC - it doesn't work when attached to an external USB hub - it does work again when I remove ehci-hcd My setup, without the hub attached, and without ehci-hcd: 0000:00:03.0 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) 0000:00:03.1 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) 0000:00:03.3 USB Controller: Silicon Integrated Systems [SiS] USB 2.0 Controller Bus 002 Device 001: ID 0000:0000 Bus 001 Device 010: ID 046d:c00e Logitech, Inc.

What could I do next to find out what's wrong? Valentijn -- http://www.openoffice.nl/ Open Office - Linux Office Solutions Valentijn Sessink [EMAIL PROTECTED]
