Oops, wrong address first time I send it by my Suse's Thunderbird,
because I checked yast2, to get the wanted information. Maybe I've
forgotten the '64', because I'm thinking of trying to use 64 Studio
32-bit on my 64-bit hardware .

Hi

I need to know the maximal possible load at 5 volts, for the Swissonic
USB device's MIDI output, connected to my ASUS M2A-VM HDMI motherboard's
ATI SB600 USB controller.

A friend said I can get this information by the Windows hardware
information, but I don't have a Windows install.

I tried lshw, yast2 and hwinfo --usb without getting the ampere.

The norm for USB 2 is 500mA at 5V, but this seems to be untrue for the
Swissonic's MIDI output.

I made a MIDI through box in the 80ies and adjusted the response
sensitivity for the MIDI input, to fit to the 80ies MIDI hardware's
outputs, maybe the standard was using TTLs.

The MIDI through box is fine with all synthesizers, it also was fine for
my old ASRock's MPU MIDI out, before I had a PC it was fine for the C64
and Atari ST, but it isn't fine when using the USB MIDI device.

Because I packed the PCB in a case that's too small, it's tricky to
close it again, after it was opened, that's the reason why I wish to
know the real maximal load that's possible for the Swissonic's MIDI
output, before I try to readjust the response sensivity.

Maybe I have to make an amplifier for the USB's MIDI output, so there
won't be the need to open my MIDI through box.

Is there any command for Linux to get hardware informations about the
maximal possible load, like there seems to be for Windows?

Cheers,
Ralf
