Hello!
I have a notebook with this sis 7001 usb-controller and sis 630
chipset.(shared memory 8mb), motherboard uniwill 340s2.
Kernel 2.2.x 2.4.1 -2.4.5
X-winows 3.x -4x.
Many low-cost notebooks have this chipset.
All works fine, like my usb-webcam, usb-scanner and my usb-zip-drive with
usb-ohci driver and the other required drivers, but only without framebuffer.
I need framebuffer,because there is no support from Xfree86 for my
Tft LCD yet.
When i use the shell,zip-drive works very stable, no errors.
When i use this frambuffer-support & X-Windows all works, but usb-devices
are crashes after short time off running..
When i use the X-server without framebuffer, i can only use 640x480 for
testing with bad display, but all usb devices works without any Errors and
very stable.
I have no Io-or Int. conflicts.
It looks like a timing problem for me, because of this problematic sis 7001,
shared memory and framebuffer.
I tested a lot, but no succes.
All devices working stable on my Destop-machines.
I donīt know, how i resolve this strange problem with using framebuffering
and usb.
