USB Controller and USB Flash drive(PEN Drive) Requirement

[VJKris]

Hi,

I have a query on deciding USB flash requirement.
Is there a relation between USB controller(in Processor) and the Pen drive size that can be connected?
Basically,if i have a USB host controller integrated in my processor,will i be able to connect a PEN drive of any size?
Or are there any practical limitation?

Regards,
VJ

The only limitation is that your software must be able to handle the file system used on the memory device. The USB mass storage device protocol doesn't care for memory size.
