Hallo everyone,
I recently bought a Sony Vaio PCG-FR285E (wrt USB equal to the 215 E), which
is a VIA based Athlon Notebook. It has three usb ports, one directly
connected to the usb root hub, the other two connected to an internal hub.
This hub doesn't seem to work with Kernel 2.4, that is, it is recognized via
/proc/usb/devices (appended) but no attached device will work. As my Kernel
(2.4.21, 2.4.22rc2 makes no difference) is homemade, to prevent it from being
the rootproblem, I tried SuSE Linux Live Eval 8.1 (Kernel 2.4.16), with the
same result. Using Kernel 2.5.75 changes the picture a bit, devices are
recognized, but the thing looked up during a regular mount/umount operation.
Beside that, this is a productive system, so I would really prefer a stable
(ie 2.4) solution.
Just to mention, all three ports are working with windowsXP as expected, so
it's not a hardware issue.
Anyone an idea? And, by the way, did anyone manage to get ehci working on a
similar configuration?
Best regards,
Jonathan Schmitt

config of Kernel:
Support for USB
Preliminary USB device Filesystem
UHCI (Intel PIIX4, VIA, ...) support - UHCI alternative doesn't change it
USB Mass Storage support
USB Human Interface Device (full HID) support
HID input layer support
are all compiled in. This is a non modular Kernel, building modules doesn't
change anything wrt this Problem
