As far as I can see, you need to close the old file descriptor and create a new one with the new direction. Never mind actually going after a chinese company internally with political connections you dont get big in china without political connections for wrong doing in the global market. You dared to suggest that those poor Chinese manufacturers might be dishonest instead of just misunderstood and discriminated against.

And for some reason, I saw this CH and had to go through the same process. According to these there exist at least the following vendor requests: Fill in your details below or click an icon to log in: Does anyone here have a description of the vendor-specific device control requests that are mentioned in revision 1.

This site uses Akismet to reduce spam. Why are most of the programmers of Arduino chips are so complicated? The WCH Windows drivers, based on some of their unintended side-behaviors, appear to be genuinely written by themselves or a contracted consulting company, etc. This is trivial to solve, just make the IP address configurable separately.

Never do business again in china. Since they are sold below market price, I suspect they paid for a batch to be made with the stolen IP from Microchip. I could not find a reason to ever design in the Microchip UART chipset — it was slow and buggy, and I believe had some irrecoverable driver crashes in some disconnect scenarios.

Prolific might have actually been okay, but from what I heard, the market has been swamped with poor quality clones, which they tried too hard to deliberately reject with their drivers. This is the question I had as well, and it is answered on the linked github https: Replying to self after having found my old notes.

But of course you are. Unlikely; the char-dev interface has been around for years now, but I see no one ever expressing interest in it, other than myself.

You can erase it but you lose the MCP code. This is close, but no cigar.

Shame they pissed off everybody with their driver shenanigans. USB is not good for precisely timed signals, which is what you need to emulate various programming interfaces.

They were also definitely better than the Microchip solution, which I believe had a much lower maximum baud rate, and quite a few reliability-breaking bugs in their code I looked at things like driver robustness to random disconnects, error rate, reliability of error flags, buffer overflow indicators, etc. Maybe someday we will be able to write little state machine engines in a high level language and download them into these dongles so that they can directly execute complex transactions with sensors etc.

That said, decapping and dieshotting is a thing, so maybe they did reverse-engineer the chip. You thus need some sort of buffer chip that streams data from the USB and translates it into the precise pulses needed to emulate whatever programming protocol. There are reasons why RS co2130 still around. The sysfs-interface only allows you to access a single GPIO-pin at a time and only allow for one operation on it linhx a time, linuz.

I find the base from which you make your suggestion Labeled on the linked page: Not sure how current they are but I sometimes find going back to older tech makes for an easier intro to newer tech. It left a poor impression. Never mind actually going after a chinese company internally with political connections you dont get big in china without political connections for wrong doing in the global market.

You can buy the wch chips in bulk cheaper than the Microchip ones. If you wire it up to a PIC programmer then it identifies itself as a 18F14K50 but with locked cp21330 flash.
