Subject: RE: New drop of schematics
I have a couple of questions, at this point, I only concern what
will be actually available in next version 442,
1. USB Device Interface
a) In your Spec, you said "The DM320 will mediate and arbitrate
all data transfers to and from the USB bus...", does this mean a device
driver (MSC for example) is needed on DM320? I thought USB is a complete
HW solution, SW USB driver will be a schedule killer unless we have some
solid ref code.
b) Will USB be able to power up the device?
c) Will USB be able to charge the device?
2. Vedio/Audio interface
Other than using a different Audio ADC/DAC, are we changing data
path compared to Ingenient's ref design? I am wondering how much low
level code can be reused.
