28 * KNOWN BUGS
29 * 1. remove/insert can sometimes result in removed state instead of inserted.
30 * This is a result of the following:
31 * symptom: dmesg shows ERMOTEIO (-121), pcscd shows -99. This can happen
32 * when a short packet is sent, as seen in uhci-usb.c, resulting from a urb
33 * from the guest requesting SPD and us returning a smaller packet.
34 * Not sure which messages trigger this.
