Any fix to get USB 2.0 working 3.8.1?

[rduke15]

Hi,

I cannot find any suggestion on how to fix the USB 2.0 problem in 3.8.1: USB 2 works at 1.1 excruciatingly slow speed.

The bug is listed on http://knoppix.net/wiki/Bugs/3.8.1 :

4. USB2.0 Storage device slow speed

[CLH] USB2.0 external hard disk is auto-mounted as ub device, which is using USB 1 transfer speed, far slower than using sd_mod. for example, trying to mount /dev/sda1 gives error because module sd_mod is not available (modprobe sd_mod gives error) should recompile kernel with scsi module (sd_mod) support. Also check out the usbmount http://usbmount.alioth.debian.org/ which automount external USB storage devices , I tried Ubuntu liveCD and it worked well at USB2 speed.

Has anyone found a solution?

Have you tried cheatcode knoppix usb2 at bootprompt. This always helped me to get 480Mbs?
