Hello all, I am posting here in hopes of getting closer to the root of this problem. I needed USB 2.0 ports on my Dell Inspiron 2650 laptop (which works great aside from this under Ubuntu Studio / Feisty!) so I decided to buy a Cables Unlimited USB 2.0 / Firewire PCMCIA card. The cardbus works fine for trivial USB devices (mouse, keyboard) but not so well for my external drive and mp3 player, which I why I needed USB 2.0 in the first place.
The hard drive, for example, mounts and appears to work, but transfers stall and it seems intermittent whether or not it's working. Sometimes it loses connectivity entirely. I am using the cardbus with the specified power adaptor (5V 1000mA) to give the devices enough power, so that shouldn't be the problem - the hard drive is powered anyway. The real manufacturer for the pcmcia guts seems to be ALi. Here is some terminal output that was requested by someone at the Ubuntu forums (I am running Ubuntu Studio 7.04, kernel 2.6.20-16 with low latency patches for audio work. I would be happy to provide more info - this is output with the hard drive and mp3 player hooked up: ~$ dmesg | grep usb [ 16.847315] usbcore: registered new interface driver usbfs [ 16.847358]
