Estamos de suerte. Leía hace un rato en el foro de minepeon lo siguiente:
Technobit released a patch for cgminer 3.8.5 that doesn't need to use hidapi.
I applied that patch and compiled manually on minepeon/rpi and then replaced the minepeon default cgminer executable and it works quite good now (btw ocs_bits default is 54 set by them in code)
you still need to use the usb 1.1 mode on RaspberryPi or it cannot initialize. While using that usb mode it seems that more than 5 Nanofurys are not possible due to Interrupt/USB bus load.

Patch (besides the TP Link openwrt image) can be found inside http://technobit.eu/0_1_3.rar
See change log notes fro compiling:
"
0.1.3 Milestone release - Nanfury support is added with native libusb api. No hid api's are required!
* cgminer ./autegen.sh --enable-hexmineru to add Nanos' manufactured by TechnoBIT known as HEXu
* cgminer --hexmineru-frequency command line to set chip frequency - range 1-62
..."
Total que me he compilado la revisión de cgminer 3.8.5 en la que Technobit ha desarrollado esto y llevo un rato minando con los NanoFury de Minerfactory. Funcionan algo mejor que con bfgminer, al menos parece dar un poco más de Hashrate. Por defecto mete 54 al bit del clock lo que hace que minen aproximadamente a 2,6 Gh/s, mientras en bfgminer con dicho valor, a parte de los continuos reinicios que sufre el dispositivo, no suele pasar de los 2,3 Gh/s. Merece la pena probarlo.
Un saludo.
