Hi,
i'm from Italy (and this is my first post on
mailinglist :) ), i have a strange issue with the ehci
module, last week i had bought an pcmcia carbus card
with usb 2.0 and firewire ports based on ALi chipset.
If i use only the ohci driver, all ports goes well and
i can use it without problems (but as usb 1.1).
When i use the ehci driver, i can't mount any pen
drive or something like that.
lspci -v give me this:
03:00.3 USB Controller: ALi Corporation USB 2.0
Controller (rev 01) (prog-if 20 [EHCI])
Subsystem: ALi Corporation Unknown device 5272

I set usb verbose debug on kernel and i get this
output for that device (with ehci):

If you need some other info, ask me. If you think that
isn't a bug of ehci-hcd driver can you tell me what
you thing about that?
Thanks.
