Subject: ohci-ssb driver on a Broadcom BCM5354
Date: Sun, 18 Nov 2007 13:23:01 -0500 [thread overview]
Message-ID: <47408305.5090804@cortland.com> (raw)
The 5354 has a dual ohci/ehci usb core. It's in an ASUS WL520gu wifi
router. The ohci hcd driver registers, but times out reading a
descriptor from the device.
Any suggestions on how to track down the problem?
I'm using 2.6.32.1 kernel from the openwrt project with the "ohci SSB
bus glue" and "Fix ohci-ssb with !CONFIG_PM" patches from linux-mips.
If there is a better test frame, let me know and I'll build it and test
that.
Is this driver known to work with some combination of Broadcom hardware?
The ohci/usb interface does work w/ the software provided with the WL520gu.
