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.
