Hi,
I'm searching and not found nothing about this problem.When I try to read 5 
bytes of one device and it can't, returns an overflow that Ican't restore the 
comunication. Any ideas?
The pyusb it's the latest in the master branch of GIT.
  File "com_usb.py", line 56, in read    return 
self.handle.bulkRead(ADMIN_MODULE_OUT_ENDPOINT, length, TIMEOUT)  File 
"usb/legacy.py", line 159, in bulkRead    return self.dev.read(endpoint, size, 
self.__claimed_interface, timeout)  File "usb/core.py", line 667, in read    
self.__get_timeout(timeout)  File "usb/backend/libusb1.py", line 550, in 
bulk_read    timeout)  File "usb/backend/libusb1.py", line 657, in __read    
_check(retval)  File "usb/backend/libusb1.py", line 407, in _check    raise 
USBError(_str_error[ret], ret, _libusb_errno[ret])usb.core.USBError: [Errno 75] 
Overflow
