Tool/software: Linux
we have a custom board piece with FTDI FT234xd converter. when the FTDI device is connected to the HOST device with OMAP2430, enumeration fails so often with following debug messages.
Linux version : 3.15
hub_irq :Something happened, let khubd figure it out [ 14.553894] omap2430_musb_interrupt : int_usb 10 , reg fc0ab000 [ 14.553894] musb-hdrc musb-hdrc.0.auto: ** IRQ peripheral usb000c tx0000 rx0000 musb-hdrc musb-hdrc.0.auto: BUS RESET as a_host
whenever this reset happens the enumeration stalls and everything that follows later fails

NOTE: other ftdi chips are working fine with OMAP4430 host device. and FT234xd board is getting enumerated in windows and linux pcs.
