I use Slackware 10 with kernel 2.6.10 on a notebook Acer Aspire 1621LM (P4 2.8Ghz, ATI MOBILITY RADEON 9100 IGP Chipset).
My problem was that all of my usb 2.0 devices (a pendrive and an external hdd) work in full speed mode (12 Mbit/s) and not in high speed mode (480 Mbit/s). In Windows XP they work in high speed without problems. In dmesg there are no errors (also with usb-storage verbose debug on). The only way I found to solve the problem is unload the usb modules and reload them in a specific order. I put in rc.local this 4 lines: rmmod ohci_hcd rmmod ehci_hcd modprobe ehci_hcd modprobe ohci_hcd With this workaround everything is fine. All details (including dmesg, usb/devices, usbtree) are listed at: http://www.linuxquestions.org/questions/showthread.php?s=&threadid=271226 Now my question is: Where is the error/bug ? In the kernel ? In the usb modules ? In a script ? I'm sorry if this is a known or old issue, but I don't find information about this anywhere. If there is a bug in the Linux kernel or the usb modules, I hope this message can help to solve it.
