I have a Serial interface board (Buslinker 2.5) form HiWonder used to control LX-16A servo motors. I am having trouble getting it to connect to my USB port on my Linux machine. It does connect once in a while and while I am using it, it seems to work well. But it usually will not connect. I can see the device with lsusb but this only tells me that it is visible from my terminal.
I ran the dmesg | tail -10 so that I could watch the connection and this is what transpired. (I left off the date/time code for clarity)
As you can see in line 5, the device connects to ttyUSB0 but then below that line something is not happy about that connection and kicks off.
usb 1-2: new full-speed USB device number 15 using xhci_hcd
usb 1-2: New USB device found, idVendor=1a86, idProduct=7523, bcdDevice= 2.64
usb 1-2: New USB device strings: Mfr=0, Product=2, SerialNumber=0
usb 1-2: Product: USB Serial ch341 1-2:1.0: ch341-uart converter detected
usb 1-2: ch341-uart converter now attached to ttyUSB0
input: BRLTTY 6.4 Linux Screen Driver Keyboard as /devices/virtual/input/input57
usb 1-2: usbfs: interface 0 claimed by ch341 while 'brltty' sets config #1
ch341-uart ttyUSB0: ch341-uart converter now disconnected from ttyUSB0
ch341 1-2:1.0: device disconnected
I was hoping someone with superior knowledge could help me troubleshoot this problem.
Thank you for listening.
