hi i was wondering if anyone out there new if there was an SDIO USB HOST card, similar to the shown on the link below (but obviously SD not CF)

if not, does anyone know/have tried the above CF to USB Host with a standard usb webcam and got it to work? if so can you explain how i go about setting it up.

thanks

i'd suspect that the fact that usb to host have to supply 5volt with 0.5mA
it could be an issue for something as thin as an sdcard
also not sure if the sdio interface even operate at 5v

I haven't seen an sdio to usb card, but I use my "htc universal" with it's mini usb as a usb 1.1 host. It works ok but you have to supply external power.

if you have that working you are the first and only person i know of who gotten any htc device act as usb host
sure there were rumors that it would do host
but later on ppl retracted those claims

After wiring up a cable for that, how do you set the phone to 'host mode'?

Thanks

usb host is not a mode
your pc is in host mode always
as are the 2 htc devices which do support
usb host out of the box

is a device is connected and the driver
is present the device works

Nope, USB host is a mode. It's the whole Master / Slave affair. Granted, it's automatic for most devices when another is connected... ah... that ought to answer my question I guess.
