This is a fresh install, and very few other modules are enabled and installed - in fact, just the prerequisites for Ubercart Attribute Files to work:
Drupal 6.25
Ubercart 6.x-2.7
User Files 6.x-1.0-beta6
Imageapi-6.x-1.10
Imagecache-6.x-2.0-beta12
Token-6.x-1.18

I created a product and set a single attribute of file upload.
In the attributes configuration, I have enabled "required".
In the product edit screen - attributes section, I have enabled the "required" checkbox as well.

When I view the product, I see the attribute, and I can apparently upload the file, or at least populate the field.
When I click on "add to cart", however, I see an error message "[attribute name] field is required". This message is repeated once (total of two identical messages).
If I remove the "required" check box from the product edit screen - attributes section, all seems to work as intended. The cart displays the file uploaded, and I've verified the file has been uploaded correctly. The problem only arises when I require the attribute file upload on the edit PRODUCT page - Setting the requirement in the main attribute configuration page seems to have no effect.

I'd guess that both UC and this module have validation code.
Assuming here you want the field to be required.

I can confirm this bug, have you guys made any progress on this?

It is kind of important in my case that this field is required. :/

same here but reverse, I do not have required checked, but when I add to cart, it gives me the error that this upload field is required.
using:
Drupal 7
ubercart
uc_attribute_files 7 .1 dev
