In the file ''usbh_msc.c'' generated for STM32F407/427 there is typo in line 446:

446 if((phost->Timer - MSC_Handle->timer) > 10000)

447 {

448 MSC_Handle->unit[MSC_Handle->current_lun].state = MSC_TEST_UNIT_READY;

449 break;

450 }

This condition makes sense if it is < instead of > because of timeout nature of it.

In the case of ''<'' this code does not connect MSC device correctly and returns debug messages like this:

Sense Key : 6<LF>

Additional Sense Code : 28<LF>

Additional Sense Code Qualifier: 0<LF>

Which means according to

that device is in ''Unit Attention'' condition and is in process of not-ready to ready transition.

Does any one meets such issue?

What should I do to report this bug to CubeMX developers team?
