Good day I'm trying to get a 2501 Ralink USB stick working. I've never had any success with it in any kernel I've tried. Right now I have the stick in my athlon 64 bit machine, Linux kernel: 2.6.30.1, and a fair bit of debugging compiled. I'd like to tap your help on getting it going, or deciding what the matter is. Firstly: lsusb output: Bus 005 Device 002: ID 148f:2573 Ralink Technology, Corp. RT2501USB Wireless Adapter (I'll add the verbose output later, but I suspect you're more interested in what the driver has to say). Loaading the rt73usb module produces this stack (after a fair old delay for the modprobe to come back) rt73usb 29288 0 crc_itu_t 2144 1 rt73usb rt2x00usb 11360 1 rt73usb rt2x00lib 33760 2 rt73usb,rt2x00usb led_class 5112 1 rt2x00lib input_polldev 4552 1 rt2x00lib mac80211 195720 2 rt2x00usb,rt2x00lib cfg80211 71000 2 rt2x00lib,mac80211 Dmesg says: [ 2108.751153] phy0 -> rt2x00usb_vendor_request: Error - Vendor Request 0x09 failed for offset 0x0000 with error -110.

Perhaps I should add an identification line somewhere in the code? Taking the stick out and reinserting it produces better output: [ 3047.942955] usb 5-1: USB disconnect, address 2 [ 3057.399019] usb 5-1: new high speed USB device using ehci_hcd and address 4 [ 3057.691030] usb 5-1: configuration #1 chosen from 1 choice [ 3057.982680] phy1 -> rt73usb_validate_eeprom: EEPROM recovery - NIC: 0xffef [ 3057.982687] phy1 -> rt73usb_validate_eeprom: EEPROM recovery - Led: 0xe000 [ 3057.982691] phy1 -> rt73usb_validate_eeprom: EEPROM recovery - RSSI OFFSET A: 0x0000 [ 3057.982915] phy1 -> rt2x00_set_chip: Info - Chipset detected - rt: 1300, rf: 0002, rev: 0002573a.

I'm connected to it from an atheros card build into my TP now. Regards, and here's hoping somebody can offer some advice.
