This should happen within the command timeout set by driver. No additional step is needed. For L2 or U3 link state, the gadget is in USB suspend.

In DWC_usb31 version 1.70a-ea06 and prior, for highspeed and fullspeed isochronous IN, BIT[15:14] of the 16-bit microframe number reported by the XferNotReady event are invalid. The driver uses this number to schedule the isochronous transfer and passes it to the START TRANSFER command. Because this number is invalid, the command may fail. If BIT[15:14] matches the internal 16-bit microframe, the START TRANSFER command will pass and the transfer will start at the scheduled time, if it is off by 1, the command will still pass, but the transfer will start 2 seconds in the future. For all other conditions, the START TRANSFER command will fail with bus-expiry. In order to workaround this issue, we can test for the correct combination of BIT[15:14] by sending START TRANSFER commands with different values of BIT[15:14]: 'b00, 'b01, 'b10, and 'b11. Each combination is 2^14 uframe apart (or 2 seconds). 4 seconds into the future will result in a bus-expiry status. As the result, within the 4 possible combinations for BIT[15:14], there will be 2 successful and 2 failure START COMMAND status. One of the 2 successful command status will result in a 2-second delay start. The smaller BIT[15:14] value is the correct combination. Since there are only 4 outcomes and the results are ordered, we can simply test 2 START TRANSFER commands with BIT[15:14] combinations 'b00 and 'b01 to deduce the smaller successful combination. Let test0 = test status for combination 'b00 and test1 = test status for 'b01 of BIT[15:14].
