Firmware update with USBasp

 

Hello TrueBlue,

Friday, December 29, 2017


There's a UK seller and he advertises that all his USBAsp devices are
RE-soldered, and when you look at them you can see the fresh flux
residues. I have never had an issue with them, nor friends who have
used them. I mention this as RE-soldering the things seems worthwhile
to this vendor to ensure 100% satisfaction to the end user. Maybe
it's worth your while going over the thing with a hot iron and liquid
flux? You can't make it any LESS useful can you? ;)

Have you tried the USBasp on another computer in case there is
some incompatibility with the first?
I spent all day on this, using three computers and two different
OSs. None recognize it. Zadig doesn't find it in "all devices.".
I'm stuck in the gate.
I even tried several distributions of live Linux to see if it was
detected under lsusb in terminal. Typically, even a non-working (or
even fake) USB device will at least show up, but it didn't. I
understand that the ATmega8 chip is supported in some kernels.
Apparently not. This was a static-bagged, sealed unit, and normally
those have been QCed, but who knows?
Assuming that the ATmega8A chip doesn't require some absent
bootloader, this unit seems to be DOA. All I get is the red LED
showing steady. I wouldn't think a common USBasp could be this
difficult to bring up, as it's a very simple device.. _._,_._,_

Yes, I've never had any problem with getting the USBasp driver installed.
So it does look as if you've been unlucky and got a bad one.
Maybe, but it appears that what I got wasn't a USBasp as we know it (and as I ordered it) after all.

I was looking this afternoon for an eBay listing of this weird device as pictured and finally found one, with this fractured description:

============================================================
No need to install the driver
The new type of latest automatic speed adjustment.
Applicable to WIN8.1/8/7/XP 32-bit/64-bit, system computer.
The product can be connected directly to the computer USB port, and the real USB reader product is connected to the target plate.
============================================================

As I dimly understand (?) it, plugging this thing into the ICSP port of a hot target device and then into the computer's USB port will result in a magical perfect connection...though (assuming no clouds of acrid smoke) I don't see how one programs anything beyond that point, as the usual applications expect the USBasp rigmarole.?

I think I'm going to stick with using the Arduino and leave this to braver and more determined experimenters with a plentiful store of 328Ps to replace the ones they'll probably brick on their march toward new knowledge.

I think that this is what many will receive when ordering USBasp devices, as it seems to be the new thing being drop-shipped for unsuspecting Chinese sellers, irrespective of product illustrations.? It may be a giant advancement for all I know (and it's obviously a more complex circuit), but it's not what I ordered nor expected.

I welcome any enlightenment from others regarding this fabulous technological advance.? I've found pictures of several slightly different PCB incarnations of this same device, so it looks like it's the coming thing.
