So if you get problematic behavior with latest compat-drivers (+ with the patch Larry pointed out), I'd say look at USB host driver of raspberry. You can check the workarounds for sunxi-ehci/ohci and tegra-ehci at: https://github.com/linux-sunxi/linux-sunxi/blob/stage/sunxi-3.4/drivers/usb/host/ehci-tegra.c#L386 https://github.com/linux-sunxi/linux-sunxi/blob/stage/sunxi-3.4/drivers/usb/host/sw_hci_sunxi.c#L633 -Jussi <snip> > > There is a major bug in rtl8192cu that was just fixed this past week.
