Title: USB 2.0 On-the-go
Post by: enaudible on July 24, 2006, 10:24:47 PM

I remember some talk about some funky boxes from China to use as a mass storage box for an R-09 or the like.

I was researching connecting my iRiver H340 to my R-09 and came across this USB OTG stuff.

For example - http://www.newegg.com/Product/Product.asp?Item=N82E16817146609 (http://www.newegg.com/Product/Product.asp?Item=N82E16817146609)

Anyone tried anything like this, or with the H340 directly, with any success? Seems like a real winner by the looks of it.

Thanks for the heads up. I have a 4 year old 2.5" Macally firewire enclosure that still works perfectly. I plan on ordering up one of these Macally USB 2.0 on-the-go drives for backing up my R-09's SD cards at festivals.

There is a good thread about these devices here http://taperssection.com/index.php?topic=65298.0;all (http://taperssection.com/index.php?topic=65298.0;all)

An On the Go (OTG) drive attaches to your recorder (or digital camera) via USB cable.  This has two disadvantages.  First, the recorder can't be used for recording while it's transferring files to the OTG drive.  Second, the recorder's battery power is used while the transfer is taking place. 

You can buy a drive with a flash card reader built in.  This  often is called a portable storage devices, or PSD.  PSDs cost more than OTGs because they include a little LCD screen that tells you what the box is doing.  OTGs just have a simple light that tells you that file copying is under way, but nothing more.

The OTG enclosure without a drive costs $50 to $75.  The PSD enclosure without a drive costs around $150.   In either case, add $75 to $100 for an 80 to 100GB hard disc.

According to a friend, the H340 apparently works fine for OTG...never tried it myself tho.  He uses it to free up space from his camera while he's travelling.

There's a pretty cool video walk-thru on how to do it over at misticriver...i'm sure this post would be a lot more helpful if i could find it............

well, use an external card reader.  and buy a second flash card.  while the first one is syncing, record onto the second one.  that way your battery power on your portable recorder is only expended recording, and you get to record while you sync.

seems like a good device and the "cons" that people list in the reviews dont seem like anything to worry about

Small note: don't confuse USB 2.0 with high speed. Although USBOTG is part of the 2.0 spec, most implementations (including the iriver h3x0) will only do full speed (11Mbps) and not high speed (480Mbps). So transfers from SD card to harddisk are not instant at all.

Also, Rockbox doesn't support USBOTG yet, and the iriver implementation will only see the first card of a multi-card reader. In my case, it only sees the CF slot and not the SD one. So beware of this, it can be quite disappointing...
