Use enum to represent table offsets rather than hard-coding numbers to avoid
problems with the numbers becoming out of sync with the table.

That should really be: [VID_MEDION_MD95700] = {USB_VID_MEDION, USB_PID_MEDION_MD95700}, since the index number is the model, not the vendor, which brings me to: [DVICO_BLUEBIRD_DVB_T_NANO_2_NFW_WARM] = {USB_VID_DVICO, USB_PID_DVICO_BLUEBIRD_DVB_T_NANO_2_NFW_WARM}, which would be excessively long. > > + _(USB_VID_MEDION, USB_PID_MEDION_MD95700), // 0 > > Please don't use c99 comments.

True. Perhaps: [DVICO_BLUEBIRD_DVB_T_NANO_2_NFW_WARM] = { USB_VID_DVICO, USB_PID_DVICO_BLUEBIRD_DVB_T_NANO_2_NFW_WARM }, Would be better, as it follows better the CodingStyle. > > > > + _(USB_VID_MEDION, USB_PID_MEDION_MD95700), // 0 > > > > Please don't use c99 comments.

In fact, they're both wrong, since there needs to be a USB_DEVICE() wrapper. David ^ permalink raw reply [flat|nested] 5+ messages in thread
