Hi,
I have a AMD Geode (embedded platform) based hardware with problems in
EHCI. Here's an excerpt from dmesg:
ohci0: <OHCI (generic) USB controller> mem 0xe0215000-0xe0215fff irq 11
at device 15.4 on pci0
ohci0: [GIANT-LOCKED]
ohci0: [ITHREAD]
usb0: OHCI version 1.0, legacy support
usb0: SMM does not respond, resetting
usb0: <OHCI (generic) USB controller> on ohci0
usb0: USB revision 1.0
uhub0: <AMD OHCI root hub, class 9/0, rev 1.00/1.00, addr 1> on usb0
uhub0: 4 ports with 4 removable, self powered
ehci0: <EHCI (generic) USB 2.0 controller> mem 0xe0216000-0xe0216fff irq
11 at device 15.5 on pci0
ehci0: pre-2.0 USB rev
device_attach: ehci0 attach returned 6
USB 1.0 works fine with cca 1 MB/s transfer rate from a flash memory
drive. EHCI capability works fine in Linux.
Here's an excerpt from pciconf -lv:
ohci0@pci0:0:15:4: class=0x0c0310 card=0x20941022 chip=0x20941022
rev=0x02 hdr=0x00
vendor = 'Advanced Micro Devices (AMD)'
device = 'CS5536 CS5536 OHCI USB Host Controller'
class = serial bus
subclass = USB
ehci0@pci0:0:15:5: class=0x0c0320 card=0x20951022 chip=0x20951022
rev=0x02 hdr=0x00
vendor = 'Advanced Micro Devices (AMD)'
device = 'CS5536 CS5536 EHCI USB Host Controller'
class = serial bus
subclass = USB
Since it works in Linux, I suppose there should be some relatively
simple quirks to make it work. Any ideas on what should I try?
