* "Fields that are larger than a byte are stored in little endian"
*
* KNOWN BUGS
* 1. remove/insert can sometimes result in removed state instead of inserted.
* This is a result of the following:
* symptom: dmesg shows ERMOTEIO (-121), pcscd shows -99. This can happen
* when a short packet is sent, as seen in uhci-usb.c, resulting from a urb
* from the guest requesting SPD and us returning a smaller packet.
* Not sure which messages trigger this.
