Hi, I have a Belkin K7SF5D7050 NIC, which is supposed to work with the p54usb driver. The original driver may be found here: http://www.belkin.com/support/article/?lid=en&aid=5381 When I extract the original firmware with the fwextract3 tool, I get the firmware which, when copied to the /lib/firmware/isl3890usb causes the following information to be logged into /var/log/messages (I use the kernel 2.6.28.7): Mar 1 14:35:21 wzab kernel: usb 2-2.1: new full speed USB device using uhci_hcd and address 5 Mar 1 14:35:21 wzab kernel: usb 2-2.1: not running at top speed; connect to a high speed hub Mar 1 14:35:21 wzab kernel: usb 2-2.1: configuration #1 chosen from 1 choice Mar 1 14:35:21 wzab kernel: cfg80211: Using static regulatory domain info Mar 1 14:35:21 wzab kernel: cfg80211: Regulatory domain: US Mar 1 14:35:21 wzab kernel: ^I(start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) Mar 1 14:35:21 wzab kernel: ^I(2402000 KHz - 2472000 KHz @ 40000 KHz), (600 mBi, 2700 mBm) Mar 1 14:35:21 wzab kernel: ^I(5170000 KHz - 5190000 KHz @ 40000 KHz), (600 mBi, 2300 mBm) Mar 1 14:35:21 wzab kernel: ^I(5190000 KHz - 5210000 KHz @ 40000 KHz), (600 mBi, 2300 mBm) Mar 1 14:35:21 wzab kernel: ^I(5210000 KHz - 5230000 KHz @ 40000 KHz), (600 mBi, 2300 mBm) Mar 1 14:35:21 wzab kernel: ^I(5230000 KHz - 5330000 KHz @ 40000 KHz), (600 mBi, 2300 mBm) Mar 1 14:35:21 wzab kernel: ^I(5735000 KHz - 5835000 KHz @ 40000 KHz), (600 mBi, 3000 mBm) Mar 1 14:35:21 wzab kernel: cfg80211: Calling CRDA for country: US Mar 1 14:35:21 wzab kernel: usb 2-2.1: firmware: requesting isl3890usb Mar 1 14:35:21 wzab kernel: p54: LM86 firmware Mar 1 14:35:21 wzab kernel: p54: FW rev 2.4.3.4 - Softmac protocol 0.1 Then the modprobe fully occupies one core of my CPU.
