Follow-up Comment #16, bug #36740 (project grub):
Hi,
I borrowed FTDI USB/serial converter to test the HW compatibility with GRUB.
Borrowed device has the same USB ID 0403:6001 - but it is FULL speed device,
not HIGH speed as Horst have. I hope it doesn't matter.
For the first look it seems to be working well - GRUB recognizes this device
and works with it (e.g. serial_usb0).
I tried connect another computer with PuTTY application to GRUB via serial
line and FTDI - to use PuTTY as second GRUB console.
I used on GRUB side these commands:
terminal_input console serial_usb0
terminal_output console serial_usb0
It worked well - I didn't find any problem.
So, I hope, if my previously mentioned/sent patch is correct, it looks You can
be satisfied :-)
(
I tested the patch on my PC if it doesn't make some regression etc. - it looks
to be OK.
But I still did not test Your (Horst) configuration, i.e. correct function of
chain EHCI -> USB 2 hub -> USB 1 hub -> low/full speed device - because I
still didn't receive USB 1 hub.
It is not so easy to get USB 1 hub nowadays, there are USB 2 only... :-(
)
BR,
Ales
