hello everyone

setup :

keil developpement board (MCBSTM32F400, STM32F407) CPU Clock : 168Mhz from HSE. USB Speed : High speed USB Class : MSC - mass storage device ULPI : STULPI01B

I use STM32F105/7, STM32F2 and STM32F4 USB on-the-go Host and device library.

problem :

I am trying to read a USB memory. If it only reads once, it succeeds. But if it reads repeatedly, an error interrupt will occur.

error interrupt :

OTG_HS host channel-x interrupt register Address offset: 0x508 + (Channel_number � 0x20) Bit7 : TXERR (RM0090 Reference manual, page 1124)

Is the solution of this error known?
