Hi there,
I believe the problem is power supply issue.
Currently, USB host ports are allowed to
supply up to 500 milliamps of power to access
USB devices. Under normal condition, the
milliamp reading under Support Information
Mode (j switch) should be more negative when
USB and other storage devices are inserted.
A likely solution would be to perform a
Service Reset (Reset with Record button) to
see if it initializes hardware. In terms of
USB devices, I recommend that you install USB
driver from HumanWare website.
Cheers,
Joseph

Subject: [Braillenote] External Drives Not
Responding
Dear Listers,
I recently acquired a 2-gig Sandisk
compactflash drive. It worked fine at first,
although I observed that, though the folder
list was short, my BrailleNote mPower (a BT
running KeySoft Version 7.2), took as much as
15 seconds to open the folder list. Now, I
am confronted with a new problem. The BN is
not recognizing any USB flash drives or
compactflash cards at all. A 4-5-6 reset
fixed the problem once, but now nothing works
at all; the drives are invisible. Oddly,
when I insert a flash card, although no "card
inserted" prompt is displayed, a "please
wait" prompt stays on the display
indefinitely when the card is removed. With
the flash drive, however, there is no
indication of its presence from the BN
whatsoever.
Any tips as to why this is happening and
how I can remedy it? Also, does anyone know
why the folder list is so slow on the flash
drives? The compactflash cards are about ten
times faster!
Thanks in advance,
Caitlin
