David Brownell24d0fb42007-10-13 23:56:32 +0200291 This driver is BROKEN because the controller which it uses
292 will easily trigger RX overrun and TX underrun errors. Using
293 low I2C clock rates may partially work around those issues
294 on some systems. Another serious problem is that there is no

739 use this driver, you will need the inputattach tool, which is part
740 of the input-utils package.
