usb issues on AMD 9xx chipset

[Nobody III]

I've been testing Genode's current compatibility with my desktop computer,
which has an AMD 9xx chipset. While the framebuffer driver works fine,
usb_drv does not.

Here's the full output:

Also, I get the following message in dmesg on linux (from
drivers/usb/host/pci-quirks.c), but not from usb_drv:
QUIRK: Enable AMD PLL fix

What might be going on? Why would usb_drv cause platform_drv to run out of
CAPs, even when I assign it 2000 CAPs (instead of 800)?
