If you compiled kernel with DEBUGFS support, you can check that by: mount -t debugfs debugfs /sys/kernel/debug/ cd /sys/kernel/debug/ieee80211/phy0/rt2800usb/register/ echo "0x001b" > eeprom_offset cat eeprom_value Second less significant bit is EXTERNAL_TX_ALC . I think your device has EXTERNAL_TX_ACL since it's older chip, but who knows ...
