USB2 timeout error
I've been having an issue today with connecting some lab equipment to my computer that has worked in the past. Connected through usb, but I cannot see /dev/ttyACM0 as I usually do. /dev/ttyUSB is also missing.
Here is the output of dmesg :
[ 337.762259] usb 2-2: new full-speed USB device number 9 using xhci_hcd [ 342.875314] usb 2-2: device descriptor read/64, error -110 [ 389.345548] usb usb2-port2: unable to enumerate USB device
I originally thought it was a permission problem, but I'm leaning now towards an issue with USB configuration or serial access. I'm still very much a noob at this though and if anyone has advice or debugging techniques for this it would be greatly appreciated!
I am running Ubuntu 4.4.0-112-generic
