Subject: Re: [usb] USB Mass Storage Class Question

** Proprietary **

hi,

for HS bulk transfers, max. packet size is 512. for FS bulk transfers, max. packet size is 64. Refer to Tables 5.9 & 5.10 of USB2.0.

This is system level question concerning Mass Storage.

 

What is the MaxPacketSize in Bulk transfers in USB2.0 (HS) mass storage
class? The mass storage class specifies 64-bytes, is this for USB1.1 only or
for USB2.0 in HS mode also?  It seems inefficient to have such a low packet
size for HS.

 

Thanks in advance,

Steve
