Hi, after upgrade from 3.16 to 3.17.2 this device isn't in lsusb output after plugging in : Bus 004 Device 002: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port (driver pl2303, usb to serial converter) The only way how to make it functional is to boot machine with connected device. But after unlug/plug the device disappeared and isn't detected again. (Probably a found once more non-functional device (USB keyboard) that wasn't detected but I thinked that problem is in keyboard...) Some other devices work fine (USB modem, flashdisk). Workaround is to downgrade to the kernel 3.16. System: debian unstable, selfcompiled vanilla, Thinkpad X61x Best regards, -- Milan Kocian -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
