Leaving aside the issue of speed this matter of getting things to be assigned the same bus addressHi KDE Control Module list these USB devices.

So I have 3 USB devices they are USB Version 1.0, USB Version 1.16, and USB Version 2.0 compliant. The Cypress Semiconductor 120GB Hard Drive is USB Version 2.0 compliant, it is connected to USB Version 1.0 Hub. This limits the speed to 12 Mbit/s. If hub was USB Version 2.0 compliant the speed would be up to 480 Mbit/s.
They all work but HD is slow and
Device: sdb = 120 GB Cypress Semiconductor USB 2.0 External Hard Drive
Problems: Sometimes mounts to /mnt/removable sometimes to /mnt/memory_card one time to /mnt/removable2
Other Drives & Storage: ImageMate CompactFlash USB Problems: Sometimes mounts to /mnt/removable sometimes to /mnt/memory_card
It seams to work best if Ext. HD is off and memory_card is in reader, I boot then turn on HD. If HD is on and memory card is not in reader I boot, them HD mounts to /mnt/memory_card, Other combonations are unpredictable.
Question
can I install some software to make Hub USB Version 2.0 compliant? If not
Is there hardware to install?
How can I get these devices to mount in same place every time.
every time is a matter for the developers. I have the same problem over another set of equipement
and especially depending, whether, a smart card is inserted, a camera is, and 3 permanent
usb devices,are connected, as well as the scsi-emulation of the writer/dvd everything gets
rearranged and nothing is constantly assigned one place. So that for instance every time I boot
up and go to use the writer programmes I have to reset the devices in the backend of x-cd-roast
and the like. The usb setup is in evolution. I don't think there is anything we can do to control
the matter ourselves.But for the most part the usb hub ought, at least it is on mine,
be static provided you don't replug any usb device. But what actually controls whether
they are connected to USB1/USB2 in the hub is still not clear to me. All right we have
both USB1/USB2 capability but how the system decides what is which isn't clear to me.
Is it the USB slots or is it the equipement or what ?
