First of all: Thank you so much for your work with cc-tool, it works well and has really helped me (after patching it).

I may have a strange cc-debugger device, that advertises itself as a RF04EB with VID: 0x11a0 and PID: 0xeb20. But it's iProduct product name is empty. Unfortunately cc-tool thinks this is an error and fails. When I deactivate those checks it works without any problems with my programmer and a CC2530.

Could you please allow empty iProduct and iManufacturer descriptors in future versions? Thanks.
