Comment (by KitsunePrefecture):
To determine the root cause of support of hardware in Haiku - first I
wanted to clarify :
Is the USB subsystem related to SBC450 ATI/AMD chipset hardware or not ?
First I learned that ATI/AMD Chipset here still classic type :
ATI Radeon* Xpress 200 Chipset -- divided to 2 parts
1. NorthBridge -- ATI Radeon* Xpress 200 NorthBridge
2. SouthBridge -- IXP 450 Southbridge
(this way detected as ''SBC450'' : **S**outh**B**ridge of **C**hipset /
IXP **450**)
From the following source below, which is about an Intel Booard with
the same chipset,
I could confirm that USB subsystem controlled by the SouthBridge of
this ATI/AMD Chipset.
DOC.LINK >>>-------> https://www.manualslib.com/manual/421428/Intel-
Blkd101ggcl.html?page=16
This document just starts withe the units description :
"The ATI Radeon Xpress 200 Northbridge is a centralized controller for
the system bus,
the memory bus,
and the PCI Express bus.
The ATI Radeon Xpress 200 Northbridge also provides
integrated graphics capabilities supporting 3D, 2D and display
capabilities.
The IXP 450 is a centralized controller for
the board's I/O paths. <===== !!! CONFIRMATION !!!
The FWH provides the nonvolatile storage of the BIOS."
In 1.5.3 part it starts to describe USB subsystem, but as it is finally
a different HW
-- an Intel board -- I just saw provide the same layout of ports as in
my laptop :
4 ports available :
--> 1 dual port - on the rear (2 ports)
--> 2 separated ports - on the front - in my case on the left side (2
ports)
both can be USB 1.1 or USB 2.0 and power as well.
Question #1 : ''**Is ATI/AMD SouthBridge SBC450 has a proper driver
support in Haiku ?**''
''I do not know how the earlier note of korli about PCI issue relates to
this
USB subsystem issue'', but
Question #2 : **''Could you confirm that - for me -''**
''**Haiku does not need chipset driver to support USB subsystem
properly ?**''
And finally the last one ... as the bootloader surely does not support
the USB subsystem
via this ATI/AMD Chipset
Question #3 : ''**Can we**'' -- who has the same chipset in different
laptops --
''**expect to get an RCA**'' from someone who would
investigate
''**why Haiku bootloader fails to detect USB
subsystem**''
''**in case ATI Radeon* Xpress 200 Chipset ?**''
Thank you in advance --
