Can you add a track mark from the computer?

[casuall002]

Is there a way to add a track mark through SonicStage on the computer...I don't have my battery/AC Adapter with me and even though it has power via USB, I can't get to any menus.

nope sorry, but you can always transfer it to the computer, divide it by audacity or whatever and transfer it back. :|

I see from the photos of the MZ-RH910 that there is a Tmark button on the unit. Isn't this what you want? I was unable to find the manual but it might be somewhere on this site.

Hope this helps.

Unfortunately, RH910's own buttons can't be used when the unit is USB-powered (i. e., connected to a 'puter).

And some immediate additional tests (ya know, "Don't trouble Avrin until...") have shown that the NH600, the NH3D, and the RH910 completely refuse to see the RH1's adapter as a source of power.

Ah, ok. There's a way of getting USB power to a unit without invoking the driver, though.

If you can avoid the proper driver getting installed, I should imagine that might get around the problem.

For instance, the RH1 comes with a PS that has a USB connector on it, and runs fine. So do some of the other units though I don't actually own one. You can buy a USB powersupply for cars too.

I would think that renaming all relevant drivers on Windoze would have the effect of turning the 'puter into a giant wall adapter, right?

[Avrin]

This has nothing to do with drivers (a Hi-MD unit in Hi-MD mode doesn't actually use any driver).

The units show "MD ---- PC" on their screens when connected to a 'puter via USB. They feel that they are connected to a 'puter. Though some are actually recharging their batteries in the transfer mode. Not the NH600, of course (it doesn't have any recharge circuitry). The RH910 does but not to the full capacity (to about 80%, as stated in the manual).

That doesn't quite make sense (yet). What is happening when a USB power supply (I have one for my GPS unit incidentally) is plugged into the RH1, then? There's no question it knows the difference (from being plugged into a computer). However the cable is a standard USB cable.

Also I challenge the statement that a HiMD unit "doesn't actually use any driver". I think you might be saying that it doesn't use any identifiable or add-on driver. But it undoubtedly uses something. How else can the unit tell the difference between PC and powersupply?

Seems to me that disabling some component in Windows might exactly trick the PC into the effect we want. Perhaps even just plugging into a powered USB hub might do it?

Notes added:

1. it looks like USBSTOR.SYS is the component that is insisting on getting installed. However I rebooted the machine and noted that even the ROM BIOS of my Thinkpad caused the RH1 to go into "online-to-PC" mode.

2. Is there a difference between the connector on the Sony supplied powersupply and a normal USB port? Or perhaps the PS is providing a different voltage so that the RH1 knows which is which?

Sounds like more fun with the charging parameters.

OK. On inspection of the power supply it seems like the outer two pins are connected (+5V aka Vcc, and 0 aka GND) but there are no "data" connections.

So to accomplish what OP wants, probably he has to sever the data lines on the USB connector whilst leaving the power lines intact.

Check, Avrin?

The RH1 senses resistance between pins 2 and 3 to determine if it is a Circuit or a Supply , the RH1 does not need a driver as you challenged , it needs to sense the presence of the computer , what is needed however is the ability to interface the software to the RH1 , the driver is for the software not the RH1

a 27 kohm resistor on pins2-3 will tell the RH1 to take the power

OK, you obviously know more electronics than I do. Will that same setup work on other units? I just now noticed Avrin's update to the #5 post in this thread (mea culpa).

(my only challenge was that some driver must be needed to communicate - but your point is that the driver consists of the various standard block and usbstor drivers, nothing specific to MD, which I have observed and agree with).

Exactly! If you do not install any PA drivers from SONY, only generic Windows drivers are used. They only tell Windows how to communicate with the device in order to transfer information. They do not seem to control power or recharging in any way (power control, as I think, is performed by USB hardware). The drivers are the same as for HD or flash USB storage.

However, if you do install the PA drivers, the SONYSDK2.inf file is also to install the SONYSDK2.sys file as a "Sony USB Mass Storage Driver", however, the file doesn't actually seem to load (at least for a [Hi]MD unit). The only difference this makes is that you can disconnect the unit without an "Unsafe device removal" warning.
