Re: [Dorset] USB 1-2 problem
I believe keyboards & mice are all USB 1.1. I have some USB 1.1 devices working on Ubuntu. If it is a 54mbit (or faster) USB device then I would expect it to be USB 2, otherwise it is limited to 11 Mb/s or thereabouts. 'lsusb -v' will show you a lot of information. The 'bcdUSB' lines show you the USB version in use by a particular device. -- Andrew. -- Next meeting: Bournemouth, Tuesday 2011-04-05 20:00 Meets, Mailing list, IRC, LinkedIn, ... http://dorset.lug.org.uk/ How to Report Bugs Effectively: http://goo.gl/4Xue
