hi,

in my card

The 88AP510 processor provides two USB 2.0 ports. The 4-channel multi TT (Translator) hub CY7C65642 is used to provide 4 high speed USB 2.0 ports on each USB interface of processor extending to total of 8 USB 2.0 ports. the power switch is TPS2561 I get enumeration error when I connect high speed and full speed devices.

Can you suggest some hardware trouble shooting
