Hello,
I am tring to use USB and having a difficulty.
I have a FIC VA503+ motherboard and AMD K6-2 500.
The motherboard has onboard VIA USB controller.
On-board VIA controller,
1. With BIOS setup menu, USB keyboard works.
2. With Win98 and DOS, USB keyboard works.
3. With FreeBSD 4.0-RELEASE, the keyboard is sometime
not recognized. When it is recognized, the keystorkes
are often lost and behaves quite erratically.
To make sure the keyboard is Ok, I put in a ADS's USB
PCI card. The card uses OPTi's chip / OHCI driver.
With this, USB keyboard works well under FreeBSD 4.0-
RELEASE.
Since Keyboard (and mouse) works OK with 98, I
am assuming the on board USB controller, wiring, etc.
are fine.
I compiled the kernel with some USB debug options
turned on. The keyboard reports status = 13 from
keyboard interrupt which is IOERROR.
I am suspecting there is a subtle timing issue in
VIA controller which is causing the problem with
UHCI driver.
Could someone help me?
Thanks.
