dzięki, a podpowiesz jak dokładnie tę instalcję przeprowadzić? Np sciagnąłem od Ciebie kmod-usb-printer_5.15.137-1_mips_24k

no i:

tylko mam problemy z instalacją pakietów potrzebnych dla usb/pendrive

root@OpenWrt:/# opkg install kmod-usb3
Unknown package 'kmod-usb3'.
Collected errors:

anyway, dzięki za pomoc, temat instalacji pakietów będę jeszcze badał

to instalowałem ręcznie, wszystkie możliwe kmod-usb
może rzeczywiście opewrt jest kompilowany bez obsługi USB na to urządzenie - ale jest jakiś sposób żeby to sprawdzić?

tu jest wspomniane że potrzebny build z obsługą USB. Ale linki do downloadu wyglądają na nieaktualne.

------------------------------ dmesg - nie wiem czy tam coś można znaleźć o USB oprócz tego że ładowane są moduły usb

Tak, próbowałem przeciąć dwie ścieżki od pinów D+/D- do chipa
5V jest zaraz obok wyprowadzeń USB
Znalazłem zdjęcie na jednym rosyjskim forum
Ale tak czy siak kicha. Może to przecięcie się nie udało, albo udało za bardzo. Generalnie to są tak maleńkie ścieżki że gołym okiem ich prawie nie widzę, a jakiekolwiek narzedzie wydaje się za duże i za tępe.
To wspomniane zdjęcia z informacją gdzie ciąć i lutować.
