I'm interested in this also !

/dev/usb/lp0 won't show up for me.

kmod-usb2 and kmod-usb-printer are installed

Unplugging/plugging printer cable yields:

[ 1441.830049] usb 2-1: USB disconnect, device number 4
[ 1446.755533] usb 2-1: new full-speed USB device number 5 using ohci-platform

Was working until I rebooted the device. Any clues?

EDIT: OK, this was incredibly nasty, but this is how you fix it:

wget these two:

http://repo.onion.io/omega2/packages/core/kmod-usb2_4.4.46-1_mipsel_24kc.ipk
http://repo.onion.io/omega2/packages/core/kmod-usb-printer_4.4.46-1_mipsel_24kc.ipk

Then opkg install both of them by filename, using the --force-depends option

It seems the LEDE repo feeds, while an interesting idea, might be too much of a moving target. Even the .ipks downloaded from the links above are not an exact match for the kernel, but on my system close enough to make things work.

I'm interested in this also !

I'm interested in this also for power-saving possibilities

I could make a strong case for nginx + ngx_http_ssl_module being enabled out of the box

However, what I need help with right now is getting ngx_http_ssl_module active at all. Has anyone managed to do this on one of our devices yet?
