Question

I am running Linux 3.0.35_4.1.0 on a custom freescale i.mx6 board similar to the Boundary devices nitrogen6x board.

The issue i'm having is that when I connect the wireless transceiver dongle for the "Microsoft Wireless Desktop 2000", the mouse works intermittently, and the keyboard does not work at all.

The HID ID of the transceiver is 045e:0745

The error in the terminal is:

Solution

A kernel configuration option "Improved Transaction Translator scheduling" (CONFIG_USB_EHCI_TT_NEWSCHED) was necessary.

This allowed the Microsoft Wireless Desktop 2000 to work flawlessly with our device.
