[Dorset] USB 1-2 problem
I recently bought off ebay a Belkin Wireless USB stick, as I had borrowed one and tried it and it worked beautifully. This one is a F5D7050 v4003 which has the same chipset (ZD1211) as my ZyXEL wireless USB stick. However when I plug in the Belkin, DMESG gets stuffed with the message “unable to enumerate USB device in port 3.” Which a bit of research seems to indicate is due to only supporting USB 1. I tried it under XP and it works fine. I even get the message that this device would work faster if plugged into a USB 2 port. I begin to wonder if this is a wobbly in XP that it cannot determine which port is USB 1, it's own or the remote? A search on the Internet brought me to: http://www.absolutelytech.com/2010/04/18/solved-unable-to-enumerate-usb-device-disabling-ehci_hcd/ Where the 'cure' is to do the following before inserting the device. cd /sys/bus/pci/drivers/ehci_hcd ls sudo sh -c 'echo -n :00:xx.x unbind' Now plug in the device and it works. 1. The question is - Does Kubuntu 10.10 not support USB 1 devices, or is the selection of version of USB faulty? 2. Belkin support tells me that this is a USB 2 device. Do you think that it is possible that they have a fault with the implementation of USB on this device (and this device only)? 3. How can I test which version of USB is implemented on a device, aside from the above(!) [ somewhere I have the spec downloaded for USB 1, but God knows where - that was years ago] Peter M. -- 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
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
