Could you open a python interpreter and run these?

import hid
import btchip
from btchip.btchipComm import HIDDongleHIDAPI, DongleWait
from btchip.btchip import btchip
from btchip.btchipUtils import compress_public_key,format_transaction, get_regular_input_script, get_p2sh_input_script
from btchip.bitcoinTransaction import bitcoinTransaction
from btchip.btchipFirmwareWizard import checkFirmware, updateFirmware
from btchip.btchipException import BTChipException

Do you get any exceptions?

thanks for the quick follow up.

Responses below - only the btchip.btchip game an error:

ok, installed the ecdsa package and that seems to have sorted it!

pip3 install ecdsa

[SomberNight]

ahh I see
how did you install Electrum?

[SomberNight]

also, how did you install btchip-python?

[techsmyth]

running electrum directly from the extracted archive (i.e. not installed)

re btchip, forget exactly where I picked up the need to install that :( Been a struggle to get this working...

relevant: LedgerHQ/btchip-python#42

[techsmyth]

thanks for addressing this, indeed two items - the missing ecdsa dependency and the error message given. Thanks for the nice work.
