* feat (hwcdc): ports changes made in 2.0.15 Ports many changes, fixes and improvements made in 2.0.15: - correct use of timeout - avoids problems with CDC ISR not reading data - fixes problems with transmitting many bytes to USB Host - changes how USB SOF and CDC connection is detected * feat (HWCDC) : port 2.0.15 Changed header for a few functions. * feat (HWCDC): port 2.0.15 upwards Fixes include file that is not necessary any more. - SOF is used directly now. * fix (HWCDC): removes left over Removes a left over function from previous 3.0.0 code. - just removing unused code. * ci(pre-commit): Apply automatic fixes * fix: typo and commentaries This fixes a few commentaries. Just a typo error. --------- Co-authored-by: pre-commit-ci-lite[bot] <117423508+pre-commit-ci-lite[bot]@users.noreply.github.com>
