Old old driver on TPLINK website ( http://www.tp-link.com/us/download/Archer-T2U.html#Driver) is NOT working: http://static.tp-link.com/res/down/soft/Archer_T2U_V1_150901.zip

One user had been kind to provide alternative driver:
https://bitbucket.org/sanrath/mediatek_mt7610u_sta_driver_linux-64bit/

[CODE]$ git clone https://bitbucket.org/sanrath/mediatek_mt7610u_sta_driver_linux-64bit
$ cd mediatek_mt7610u_sta_driver_linux-64bit
$ vi common/rtusb_dev_id.c
$ make
$ make install
$ modprobe mt7610u_sta[/CODE]

After adding the following line into the ./common/rtusb_dev_id.c (as per codes from ./Archer_T2U_V1_150901/Driver/NETIF/common/rtusb_dev_id.c), the driver can detect Archer T2U USB but is not able to work (getting segmentation fault on the ModemManager)

[CODE]#if 1
{USB_DEVICE(0x148F,0x761A)}, /* T2Uv1 */
{USB_DEVICE(0x2357,0x0105)}, /* T1Uv1 */
#endif[/CODE]

Kindly please advice.

Ubuntu 16.04 and RHEL 7 are the current up-to-date Linux releases.

Please provide support to this Archer T2U USB driver
