There were a lot of entries as the result of lsusb -v since there are many devices on the system, so I have just pasted the entries containing ID 2b3e. Please let me know if this is insufficient, and I can provide the entire output in a file.
cat /etc/udev/rules.d/50-newae.rules:
## NewAE .rules file to enable ChipWhisperer to easily take control
#
# To use this file
# 1) Unplug all NewAE hardware
# 2) Copy to /etc/udev/rules.d/
# 3) Reset the udev system:
# $ sudo udevadm control --reload-rules
# 4) Log in/out again for changes to take effect
# 5) Connect hardware
#
# Match all CW devices
SUBSYSTEM==“usb”, ATTRS{idVendor}==“2b3e”, ATTRS{idProduct}==“ace[0-9]|c[3-6][0-9][0-9]”, TAG+=“uaccess”
From lsusb, it seems there is some issue in opening the devices.
Here is some additional information from dmesg yielded from plugging in the devices in case it is of relevance:
