2010-03-13 03:00:07     is it possible to connect more than 1 usb devices to BF52x

I found this "it can not support USB Hub devices as a host. (You can not plug a hub into the USB controller found on the BF54x or BF52x)" in   docs.blackfin.uclinux.org/doku.php?id=linux-kernel:drivers:musb&s#usb_otg_support.

 

Is that mean it is impossible to connect more than 1 usb device to BF52x?

 

Regards,

If I want more USB device in my system, the only way is to use an external USB HOST controller?

I have an question in another thread(  blackfin.uclinux.org/gf/project/uclinux-dist/forum/?_forum_action=ForumMessageBrowse&thread_id=39827&action=ForumBrowse&forum_id=39), I want to connect a USB DISK to BF526EZBRD, but it seems BF526EZBRD can not detect the USB DISK plugin. Which cable should I use?
