Coexisting with WiFi
1. How exactly does the CY4632 WirelessUSB LS KBM RDK cope with the situation where it is occupying a ISM channel when someone switches on a 802.11 network which occupies the same channel. Will the keyboard malfunction momentarily? Will it cause keyboard / mouse errors?
How long does it take from initially detecting interference on PERT to high or RSSI to re-locate to a clean channel and rebind? Will this have an effect on the keyboard or mouse operation being used?

Passive feed through for USB signals
Is it acceptable to have a circuit board act as a passive feed through for USB signals? Specifically, what we wish to do is to have two single USB "Type B" connectors adjacent to one another on one side of the board and a dual-row "Type A" connector on the other. Pin-for-pin connections exist as printed traces on the board but there is no filtering or electrical "buffering" on the board; the connections, therefore, are totally passive. Is this sort of passive pass-through acceptable?

SUDPTR
Can the USB core tell whether or not SUDPTR is pointing to a descriptor.If SUDPTR is pointing to vendor-specific information (instead of a USB defined descriptor) the second case stated in the TRM as follows
"The USB core transfers the lesser of (a) the bytes requested in the SETUP packet, and (b) the bytes in the length field pointed to by the SUDPTR"
is not applicable. How is this implemented? Also how is the entire configuration descriptor (with interface, endpoint descriptors) sent within one request if the SUDPTR is pointing to the configuration descriptor and the first byte in the descriptor states only 9 bytes.
