⦁ Removed `import time` (not used) ⦁ Removed unused/duplicate `_Device.config` argument `config_str` ⦁ Fixed the loop reserving other string indexes used by built-in drivers `while len(strs) < builtin_driver.str_max:` to `while len(strs) < builtin\_driver.str\_max - 1:` (row 169)because str_max equals to one more than the highest string descriptor index value used by any built-in descriptor according to the [docs](https://docs.micropython.org/en/latest/library/machine.USBDevice.html) and added a comment that this loop is probably unnecessary or even wrong ⦁ Added `bAlternateSetting` as argument to `Descriptor.interface`, because it is used for USB MIDI 2.0 ⦁ Some code optimisations
