Please log in for more thread options Thank you for the email address and further reply. At the bottom of this
webpage:
http://www.pocketpcfaq.com/faqs/activesync/usb-advanced-functionality.htm it
mentions that unchecking the Enable Advanced Network Functionality box
disables RNDIS and enables PPP again. I don't know why but I confused RAPI
with RNDIS, it's RNDIS that I've disabled. If Activesync uses RAPI for data
transfer and that incurs a significant overhead, perhaps MS can consider
using whatever the memory card reader transfer relies on instead... I'll
suggest that to them in my email.

>> Thank you for the reply. As it happens I did come across your pocketpcfaq
