I have not force openssl to 1.1 at https://github.com/nxp-imx/mfgtools/blob/master/libuuu/CMakeLists.txt If not SSL, just https will not supported. Basic function should work.

FBK needn't timeout. if timeout happen, it should be something wrong.

usb bulk transfer is guaranteed by usb protocol. Hardware will do retry if driver work correct.

I remember it is 2s. best regards Frank Li

FB[-t 10000]: ucmd It is correct. If you run as command line uuu "FB[-t 1000]:" ucmd if it is script. " is not needed. -t time only support FB. FBK...

actual_lenght actually is not used. I remember the caller always split into 64k for each transfer to avoid single transfer hit timeout.

If usb low level transfer is okay, timeout only happen when device side have not queue transfer on time.

It is not necessary to turn max_packet_size here, we just set a safety value such as 64k before we really met performance problem when use small max_packet_size. HID, HID report...

Yes, but the root cause should be PI usb host driver. I think any work around here should not resolve problem 100%.
