--- Comment #5 from j...@transactionware.com --- (In reply to Hans Petter Selasky from comment #4) I do not believe they are firmware upgradeable. A naïve reading of the USB trace by just looking at the USB HID key codes, gives me this sequence of events, from the 'c' keyboard down event.

I'm not sure how "counntu" could come from that sequence of events. With the 'u' at the end of the keystrokes that made it to userland, it almost looks like the packets were processed out of order. Is that possible? -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-usb@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "freebsd-usb-unsubscr...@freebsd.org"
