Unlocking AsusWRT USB over IP server

[berga_d]

Hi, I've found that AsusWRT firmware includes USB/IP support through the “u2ec” daemon in /usr/sbin/.

This is an USB over IP SDK from Eltima that should support every USB device.

However it seems to have been locked down to specific usb classes like printers in router firmware.

Is there any modder interested in working on this feature?

I think a lot of users will be fascinated for the many uses of a remote usb server, from audio streaming (playing/recording), video camera surveillance, IR blasters, and many others. USB Servers often cost around 40-60$.

UPDATE
Probably the only necessary patch is against "src/router/u2ec/testusb.c".
The printer test in "testusb()" must be removed, and then usb redirection should be enabled with "echo a > /var/u2ec_fifo".

I know this is old, but, do you have the u2ec source code? If so, how'd you get it?

The source code is available in the "Driver & Tools > Others" category for your particular model on the the Asus website.

Not for u2ec. I've pulled the GPL release for several models and they only contain the stripped u2ec binary. No source.

I see. It looks like the OP was referencing this build:

asuswrt-merlin/release/src/router/u2ec at 68a34ba08be12bb965cee6fc993a4863f8f0c1e5 · RMerl/asuswrt-merlin
