When TEST UNIT READY, some USB Drives and SD Card Readers respond with sense_key: 0x06, code: 0x28, qualifier: 0x00 NOT READY TO READY TRANSITION - MEDIA CHANGED. In order to clear this code, a REQUEST SENSE needs to be performed before repeating TEST UNIT READY.
If the unit is ready, there is a quick return from the msc_wait_for_ready_state function. The previous code caused a minimum 100ms delay before returning, even if the MSC device was ready.
WAIT_FOR_READY_TIMEOUT_MS was increased to 5000ms, because some USB Drives were timing out with the old value of 3000ms.
