A700 USB Remote Request "bit 0x00000008" - fingalo?

Hi,

I've got a A700 without USB Remote Support  :(

I've checked the misc values (I think this are the I/O-Ports?!)

in Record Mode without USB
1:  8c894885
2:  fcdc0fe0
3: bfff
4: 0

In (1) and (2) some higher bits toggle continously, the lowest nibble change to 'd' if USB is connected.
So, I think the right bit is "0x00000008"

In Playback Mode the lowest nibble of (1) change from '0' to '8', so I think, '8' is the right bit position.

Maybe someone could integrate it and give me a feedback to test it.

Thanks in advance! Btw you're doing a great work.

I will send you a copy of SDM.

You can use the normal USB switch or a Ricoh CA-1 remote.

You do not need to run a script.

I've downloaded the software from the link



I said that I would send you the software.
The webpage link was only for details of the Ricoh switch.

You need to know how it works.

Hi StompSC,

recently I build me a sound trigger which sets a 5V to the USB of my A700, but unfortunately USB has not been suppurted yet. Then I found this thread and tried out what you mentioned above... and it works  :) There where only two minor changes in the allbest source code. I just add some lines, compiled it and it works:

Thanks alot. Now I will try my sound trigger.
By the way I am new here. So is there any centralized place where new stuff, fixes ... are collected.

It's great! Add this to AllBest's Build.

I have one question: what battery do you use? 1.5V with some 5V regulator?

I do not believe this is correct.
I asked 'garcia'  to confirm it but received no reply to my email.

It should be #define USB_REG 0.

An SDM tester has confirmed this works.

That means the trunk version is also incorrect.
