Have the same problem, suspecting USB clock. C5509A has optional
APLL for USB clock generation which according to TI should solve
the problem. Have not had time to verify by myself yet.

TI has now documents available for USB DPLL to APLL migration and
5509 to 5509A migration.

Another note about interrupts: C5509A seems to have Smith trigger
inputs for INT[0..4] and RESET pins.
