Hi all,

just installed ubuntu studio 12.04.2. Everything seems to work fine so far except USB, which works only for external drives and pen drives.

I have tried two external USB mice (logitech notebook external mouse plus and trus predator gamer mouse) and two USB audio interfaces (tascam us-800 and lexicon omega). In all cases, the external storage mounts and opens a Nautilus window when inserted, but plugging a mouse or an audio interface causes no visible activitiy whatsoever, and the audio interfaces indicate no usb connectivity as well.

dmesg and lsusb reveal this as well--when plugging the hard drives you can see activity, but the mouses (mice?) or interfaces don't appear in either dmesg or lsusb. these are optical mice and the laser doesn't light either upon plugging as it normally does. it simply flashes once on plugging or unplugging.

i have tried all three usb ports.

I have used all this hardware on this computer with AVLinux and Ubuntu 12.04 and it works fine, but with Ubuntu Studio (which seems great in all other respects), it's totally failed. Please help!

Thanks

Dan
