Dobrý den,

prisily mi Gadgets a nedari se mi stabilne pripojit k donglu:

Na USB1 portu jsem mel pripojeny 500GB USB disk a na
     USB2 portu ctyz portovi USB hub a v nem cidlo DS18B20 pres USB2Serial prevodnik Prolific - vse funkcni

Pro zjednoduseni jsem vse odpojil a rebootoval Turrise.

pak nainstaloval
opkg install kmod-usb-serial-ftdi

a vetknul dongl do portu USB1:
error v dmes:

ttyUSBx se nevytvori

Pokud dongl vetknu do USB2:

Overil jsem si ze se jedna o problém v routeru Turris - Gadgets:Dongl je plne funkcni, ověreno s jinymi zažízeními.

K erroru v dmesg jsem vygooglil toto:
http://patchwork.ozlabs.org/patch/306740/
Patchwork [3.8.y.z,extended,stable] Patch "USB: ftdi_sio: fixed handling of unsupported CSIZE setting" has been added to staging queue

ale nedokazu posoudit zda je patch v turris repository aplikovany ci nikoli …
Dovolil jsem si dotaz prelogovat do oddílu "Technická podpora" protože si myslim ze sem patri.

Do re-flashe routeru se mi zatim moc nechce, prece jen mam imlementovano dost rozsireni.
Třeba mi někdo poradíte …

s pozdravem
Petr
