Firmware load error connecting multiple TP-Link AR9271 wireless devices to olimexEdit
When we connect 2 or more TP-Link AR9271 wireless devices to olimex board its likely that we will see this error.
usb 5-1: firmware: failed to load ath9k_htc/htc_9271-1.4.0.fw (-2)
usb 5-1: Direct firmware load for ath9k_htc/htc_9271-1.4.0.fw failed with error -2
lsusb will list all the devices but won't create wireless wlx***** device, please check check with
ip a command. Main cause of this problem is lack of sufficient power to TP-Link devices. To solve this issue connect all TP-Link wireless devices to USB extension with external power [This is very important because by default power is supplied to TP-Link devices via olimex board through USB cables, since they are directly connected and olimex can't provide addition power (Need to work on exactly how much power is required and is supplied) we have to provide external power which can be activated by using USB extension with power].
