I wanted to install the ESC/POS Hardware Driver module By OpenERP SA. The server answers


Unable to install module "hw_escpos" because an external dependency is not met: No module named usb.core

What shall I do? as I don't know how and from where to install the external dependency named usb.core?

As far as I am using the OpenErp Saas environment, I have no way to install this module. I would expect OpenErp to implement this on their commercial server.

Hi Jagdish,


Thx for answering However those instructions cannot be executed on a SAAS environment, making me try to understand why module hw_escpos is made available in SAAS while this dependency to usb.core cannot be met?

Looking forward to your clarification.
