/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:
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.
