1. Missing break in readDevice() Bulk case: Bulk read result was
overwritten by interrupt read, silently corrupting all bulk reads.
2. Wrong variable in writeDevice(): switch checked ep_read instead
of ep_write; Interrupt case used ep_read.address for writes.
3. Interface mismatch in closeDevice(): always released interface 0
(intefrace_) instead of the actually claimed interface
(interface_claimed), leaking non-zero interface claims.
4. Wrong index in interface enumeration: used outer loop variable c
(configuration index) instead of i (interface index), reading
wrong interface descriptors or causing OOB access.
