Hello,
i have an older server that only has usb 1.1 ports and attached a
"Siemens Gigaset USB Adapter 54 V2" (chip: ISL3887, vid/pid:
0x083a/0x4521), with the firmware
http://daemonizer.de/prism54/prism54-fw/fw-usb/2.13.25.0.lm87.arm the
device comes up and everything looks fine.
the only problem is, that hostapd does not work correctly, no wlan
client can connect (but the device is in their list).
because i read somewhere that usb1.1 together with this device is not
working correctly with hostapd, i tried it on a different machine,
routed the device through virtual box usb driver and there it was
working perfect; to check that its really a usb1.1 problem, i disabled
the usb2.0 controllers and retried on that same machine -> not working,
same behaviour as on the older server; i tested it again with usb 2.0 ->
worked, 1.1 -> non working, 2.0 -> working.
so it looks like there is something bahving wrong if the device is
connected to an usb 1.0/1.1 port.
im willing to debug this stuff if i get some pointers...
regards,
Kristoffer Janke

My Dell DW1450, which uses p54usb, does not work at all on a USB1.1 port. I
tried with 3.3-rc1 from wireless-testing and with a 2.6.30 kernel. The failure
does not appear to be a regression. With a 3.2 kernel, it it works fine on
USB2.0 ports.
