@leonelhs in case you still have your macOS notes, I am trying to use a cheap CH341 (from AliExpress circa 2023) to detect on macOS Ventura (X64) and this is as far as I get:

$ sudo ./ch341prog  -i
libusb: info [darwin_detach_kernel_driver] no capture entitlements. may not be able to detach the kernel driver for this device
libusb: info [darwin_claim_interface] no interface found; setting configuration: 1
libusb: info [darwin_claim_interface] interface not found
Failed to claim interface 0: 'Input/output error'

$ sudo ./ch341prog  -i
Device reported its revision [4.03]
Chip not found or missed in ch341a. Check connection

$ sudo ./ch341prog  -i
Device reported its revision [4.03]
Chip not found or missed in ch341a. Check connection
...

The same cycle repeats after unplugging/replugging the programmer. I am wondering if this is a macOS issue. I have libusb 1.0.26.

Here are the debug logs for first execution (if you have time to compare with yours?):

$ LIBUSB_DEBUG=100 sudo -E ./ch341prog  -i
