	Hello, I m very confused of my debugger. I PCB isolation milled the connections for hardware debugging my esp32 wroom d1 mini with ft2232h mini modul. Eveything worked more than a year but today I m getting stupid error For bug reports, read http://openocd.org/doc/doxygen/bugs.html debug_level: 2 adapter speed: 2000 kHz Info : Configured 2 cores esp32 interrupt mask on **[vMicro]** Uploading App :Error: libusb_open() failed with LIBUSB_ERROR_NOT_SUPPORTED Info : clock speed 2000 kHz Error: JTAG scan chain interrogation failed: all ones Error: Check JTAG interface, timings, target power, etc. Error: Trying to use configured scan chain anyway... Error: esp32.cpu0: IR capture error; saw 0x1f not 0x01 Warn : Bypassing JTAG setup events due to errors Info : Listening on port 3333 for gdb connections Error: JTAG scan chain interrogation failed: all ones Error: Check JTAG interface, timings, target power, etc. Error: Trying to use configured scan chain anyway... Error: esp32.cpu0: IR capture error; saw 0x1f not 0x01 Warn : Bypassing JTAG setup events due to errors Error during upload using programmer The uploader process failed The uploader process failed The uploader returned an error output also attached! Also add one picture of my debugger.. can not think that ther is a problem on my milled pcb. Also isolated the blank copper pcb after milling with isolation coatting. Thank you very much in advance for help!! Christoph

	Thanks for the report. If the PCB is known to work, and all connections are still correct it does seem unlikely it is a hardware issue. Can you confirm your software on the ESP32 is not using any of the JTAG debugging pins for IO? Do all connections for the debugger test correctly with a multi meter?

	Thank you for your respond! Tried simple led blink with built in LED and nothing else -> working Akward!! I used IO13 in my code and did not recognized this change. Again thank you very much !! Christoph
