There are very cheap Arduino clones with CH340G chip for USB communication. Unfortunately, this chip need special driver (you can download it from vendor's web page), has documentation in Chinese only and cannot identify itself to computer via USB 3.0, so it seems as bad choice for Reprap universe. Anyway, for applications without USB communication can serve as other clones. Personally, I have no problem with this chip on Debian Linux (both 32 and 64 bit) and USB 2.0. https://reprap.org/forum/read.php?13,440242,440242#msg-440242 Mon, 05 Oct 2026 10:41:14 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,440242,440394#msg-440394 https://reprap.org/forum/read.php?13,440242,440394#msg-440394 Dust Controllers Sat, 06 Dec 2014 08:29:06 -0500 https://reprap.org/forum/read.php?13,440242,440334#msg-440334 https://reprap.org/forum/read.php?13,440242,440334#msg-440334
Anyway, I am not sure if the problem is USB 3.0 or some specific USB controllers (and have no intention to make some further experiments here). Simple, this chip doesn't work "out of box" like Mega16AU or FTDI.]]> Brundibar Controllers Sat, 06 Dec 2014 05:30:21 -0500 https://reprap.org/forum/read.php?13,440242,440278#msg-440278 https://reprap.org/forum/read.php?13,440242,440278#msg-440278 forums.reprap.org]

The not compatible with usb3 is new info though]]> Dust Controllers Fri, 05 Dec 2014 21:23:50 -0500 https://reprap.org/forum/read.php?13,440242,440242#msg-440242 https://reprap.org/forum/read.php?13,440242,440242#msg-440242
