Is it possible to use a USB SD card reader with the new SN10 USB
port? Apparently, Winscore prefers SD-type media over USB thumbdrives
when it comes to fast downloading of .igc files, so in the interest of
keeping contest scorers happy, inquiring minds want to know.

Of course, I could just go out to the glider and try it, but that
can't happen till this weekend...

Woohoo, contest season is firing up!

There should be no difference in what the USB adapter would see with
an USB thumb drive vs. a USB to SD card adapter. Obviously test with
your SD card adapter.

I don't see why Winscore or a CD would care about a thumbdrive vs. an
SD card. Somebody has a really fast USB2 or Firewire SD card reader
and is comparign that to a USB memory stick (which differ in
performance like SD cards do) and the performance in copying a several
100 kbyte or so file to the computer hard drive is significant?

Two part answer:

(1) Winscore, or any scoring program, could care less what
kind of media used for the files. The scorer may however
complain if you show up with 5.25" floppy disks.

(2) There are adapters that take a uSD card and make it
look like a USB thumb-drive. The one I have takes too
much power and doesn't work with the ILEC-SN10-USB
adapter.

Hope that helps,
See ya, Dave

Winscore doesn't care. However the operating system does take a while
longer to recognize a USB drive. Experience shows that SD cards beat
any other option in the scoring shack by a country mile.

What are scorers using for the OS - Win 98? Me? My XP computers find and
display a USB drive in 5-6 seconds vs 4-5 seconds for an SD card, not
enough time to go that country mile, even with 50 entrants. Does the
problem come from having 50 different USB drives, instead just 5 or 6
different ones?

I also had trouble seeing a significant delay, and I was running
Windows 2000 under VMWare Fusion on a MacBook Pro (so some additional
overhead for device I/O though the virtualization software). There was
no noticeable difference in device detection speeds.

The internal operation of just about every internal SD card reader is
actually a USB interface, same with ExpressCard SD card readers.
PCMCIA is a bit different, but I'm surprised there would be a big
overhead just for USB device discovery. Is something strange going on
with autoplay?

I assume Dave's earlier comment about power consumption of USB to SD
card adapters referred to some of the larger desktop style ones, the
typical small SD to USB small adapters like my SanDisk MicroMate or
SimpleTech Bonzai draw very low currents. I don't have my USB breakout
cable handy or I'd measure the currents but I know it is low.

Leo (Buckley) could tell you more, but afaik he doesn't read r.a.s.
On his system -- I've watched this -- SD cards are recognized much
faster than USB drives. If we all used USB drives with identical
drivers it would probably be a non-issue.

I have a small converter that looks like a normal USB memory
stick, with a tiny slot in the end for a uSD card (I use this for
turning in FLARM log files). The combo (adapter plus uSD card)
draws > 100ma, which is the max our adapter sources.

What it needs all that power for I have no idea...
Your mileage may vary !

Best Regards, Dave

PS: In windows device manager, switch to connection view,
and you can see the USB current for each connected device.
No need for breakout cables...

You don't need to be in connection view do you?

Anyhow this does not work in a virtual machine like I am running. My
God, people still run Windows on native hardware? I keep mine locked
tightly is a safe container on the shelf and only open it when needed.

I opened Device Manager, located my USB memory stick in the USB
controller list, opened Properties, but don't see power or current
listed in any of the tabs. The Generic hub did have a Power tab, but it
showed the requirement for the attached device (auxiliary display), not
actual current. Can you be more specific on which USB to look at, and
where in the Properties?

Could it be that the scorer usually has the SD card reader plugged in
and recognized by the computer and that somehow speeds the mounting of
individual contestants' SD cards whereas the USB drives need to get
recognized independently for each contestant?

Here's an excerpt from the email Leo sent out to R5 entrants (all 65
of 'em):

"So, my preference for flight logs is the following:

1 – Memory Cards such as “Secure Digital” or “Compact Flash”

2 – USB Thumbdrives. These take longer than memory cards because the
operating system has to find a driver and load it for each Thumbdrive
the first time the computer sees the Thumbdrive. Succeeding reads
take less time but are still slower than memory cards because the
drive has to be installed.

There is one other problem, which is mostly with “Cruzer”
thumbdrives. These seem to have programs on them that automatically
start and run, which totally blocks my computer from reading the
flight log. So, please, NO Cruzers. Instead get an ordinary cheap
small thumbdrive and use it.

3- 3 ½ inch Floppy Disks. Although pretty obsolete, I can still read
them.

4– Direct downloads from Loggers.

A - I have the hardware and software to download the older Cambridge
Model 10, 20, or 25 loggers.

B – I have the hardware and software to download Volksloggers with
the RJ-11 connector.

C – EWA Microrecorders have a USB connection and behave like a
thumbdrive ."

Its the easiest way to find the hub controlling your device,
which is where you need to look at the power.

Depending on *which* virtualization scheme you are using
and its USB support, it may work. USB doesn't work in free
VirtualBox for example...

Start with "View by Connection".
Locate the USB hub controlling your device.
Look at properties, power tab...

This shows the max current negotiated (max to be provided
by USB host), not the instantaneous actual current.

Hope that helps,
