No, this is wrong. For many years there has been two in anoncvs. Recently one for the AT91 was added. There is also a driver for the DS12 soon to be added soon and i know of two other drivers which have been written and might get added. There has been a recent boom in USB! > (I know documentation doesn't always keep up with > the code base.) Is the lack of USB drivers due to flaws in eCos, a > steep learning curve, no need for USB drivers, or something else? I think it has been lack of need. However USB itself can be hard to get right, so don't underestimate the learning curve, time, tools, silicom bugs etc. > Where is that USB device driver located in the repository? packages/devs/usb > Has anyone added isocronous transfer support to the eCos USB base?
