Satellite Pro A300 can not find USB devices

Hello forum,
we have a costumer who has bought a Toshiba Satelite Pro A300 from us, but he gets a strange error on it.
he connects a Sandberg USB 2.0 5port Hub to one of the usb ports, the pc finds the hub, but when he connects a memory stick to the hub nothing happens.
the hub and memory stick works on others pc's.
hope somebody can help.
best regards

Hi
What happens if you connect the memory stick directly without this USB hub?
I had also an USB hub but these hubs are a little bit complicated and tricky The USB specifications allows a certain power and depending on the devices that you connect you have to use an active USB hub, that means with external power supply.
But normally Satellite Pro A300 should have enough USB ports If its necessary I would recommend an USB hub with 2 or 3 ports maximum

Welcome to the Apple community.
A number of people have reported similar issues recently, many appear to have found a discrepancy of some kind in their account settings and making changes to these settings or simply resetting them has resolved the matter.
Check your account details are correct, check that you are using the correct details for Location, Region and Time Zone. You may want to change these settings and then change them back to see if that helps.
You might also try logging out of and then back into your iTunes account (Settings > iTunes Store > Apple ID’s > Sign Out) and restarting your router. (Some have reported that after doing this, they need to check for rentals even though it may report that there aren’t any, after which rentals once again appear in the ‘movies’ feature)
Rentals should appear under their own heading in the ‘Movies’ feature, you might also check at Settings > iTunes Store > Check For Rentals.

Installing windows 7 on mac pro retina, can not find cd/dvd driver

Hi there, I have bought mac pro retina. Trying to install windows 7, running boot camp. I have downloaded windows support pac on the same usb flush. When running instalation, the system is looking for cd/dvd driver. Even though I browse to the usb flush. It can not find the driver. Than I can not go futher. Anny ideas?Thank you so much

Could be you khave a corrupted Win 7 install file/files.
Try downloading the Win 7 ISO for the version you have from here.
http://www.mydigitallife.info/download-windows-7-iso-official-32-bit-and-64-bit- direct-download-links/
Then burn that ISO to a USB or DVD, USB would be better.

I have a compaq 6200 pro i can not find the driver for SM bus controller.

I down graded the 6200 pro with the i3 chip to winXP and now I can not find the driver for the SM bus controller does this system have a sm bus controller?

Hi: Please click on the device in the device manager. Then click on the details tab. Post the top string of characters you see. Those will identify the type and model of the missing device and I can send you the link to the drivers. It is either your AMT driver, TPM driver or IMEI driver. In the meantime, install the chipset driver and reboot if you have not done so already. http://h20000.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?lang=en&cc=us&prodTypeId=12454&prodSeriesId=5037900&prodNameId=5037902&swEnvOID=1093&swLang=13&mode=2&taskId=135&swItem=vc-88640-1 Paul

Satellite A205 S4797 - can not find drivers for my drive

I have recovery disks and Windows Vista installation disk. When I try to install error meesage says it can not find drivers for my drive.
I tried scannong CD drive and it cannot find them do 32-bit, 64-bit all have different drivers and if so where do I get the one I need if not from the install disk or recovery disk from manuf.?

If you cannot use original Toshiba recovery DVD for OS installation I can imagine there is some problem with DVD itself (some missing file or scratch) but Microsoft Vista installation MUST work on this notebook model.
If this doesnt work too there must be some problem with HDD. Just if you want to install WXP you need to load SATA driver at start-up but Vista must work.
Can you please tell me what happen when you try to install Vista from Microsoft Vista installations DVD?

VirtualBox Can't Find USB Devices

Hi all,
Just run into a USB issue in VirtualBox, I tried everything I can find on internet, but nothing fixes it.
It used to work fine before, I don't know when was it broken. Here's some information:
I'm running VirtualBox 4.2.6 on Linux 3.6.11-1-ARCH.
I added myself to vboxusers, and I have
export VBOX_USB=usbfs
in ~/.xinitrc
I also have VirtualBox extension pack installed.
Now the weird part is, I can access USB devices if I run VirtualBox with root privilege, while with my own account, it shows the following error message once I click "Settings" button:
Failed to access USB subsystem.
Could not load the Host USB Proxy service: VERR_NOT_FOUND.
Anyone has any idea what's going on?

Guys.
Was there a solution found?
I get the same error on current (fully updated) install.

ls -lR /dev/vboxusb

Some other page wrote:

BUT I double checked before adding it...
Terminal wrote:[root@wishmacer andrzejl]# ls /proc/bus/usb
ls: cannot access /proc/bus/usb: No such file or directory

SO... There is no such folder - the mount would fail...
Here I can see the info:

/proc/bus/usb is removed from kernel 3.5.0. That is the problem?
Basically I have spent the last 3 or 4 hours (maybe more) trying to figure this out on my own - I thought it would be a good idea to report this here as this thread is similar (to say the least) to my case and then keep searching for a solution to this annoyance.
Regards.

Re: Satellite Pro A40 - Can't find boot order in BIOS

Hi, we have a very old Satellite Pro A40 with a new hard drive.
We're tryng to change the boot order in BIOS to recognise the CD drive ready for the windows disk. However, there seems to be no option to change the BIOS boot order and yes we've tried the Toshiba route which suggests pressing C during boot up and F12 to select the drive during boot up, neither of which work.
Please can someone help?
regards
Karl
PS: The current message on the screen during boot up is BOOTMGR is missing

Hi karl1966,
Have you checked if the CD/DVD drive is recognized properly in BIOS?
Maybe your disk is scratchy and you should try another one. I dont know which disk you have used but try it with Toshiba recovery disk and Microsoft Windows disk.

I can not find my device (I Pad) when connected to my desktop.

I am unable to find my device (IPad) in ITunes when when connected.

Hi guys,
I got a strange problem. I HAD a working tv-out with my beyond kernel. I updated my system:
starting full system upgrade
[06/08/06 21:41] removed nvidia (1.0.8178-16)
[06/08/06 21:42] upgraded codecs (20050412-2 -> 20060501-3)
[06/08/06 21:42] warning: extracting /boot/kconfig26 as /boot/kconfig26.pacnew
[06/08/06 21:42] upgraded kernel26 (2.6.16.19-1 -> 2.6.16.20-1)
[06/08/06 21:42] installed nvidia-utils (1.0.8762-4)
[06/08/06 21:46] installed nvidia-beyond (1.0.8762-1)
After that I can not use my sweet tv-out anymore. As u can see I have used nvidia driver with my beyond kernel so I installed the nvidia-beyond instead.
Can some one tell me what went wrong??

Well if u mean if I removed the old nvidia driver then yes. I am currently having two kernels one is my beyond and the other is the standard one. So for the moment I am running beyond kernel with beyond nvidia....and I also got nvidia-utils installed since the driver wants it. I got dual boot I started up windows and in that OS my tv-out is working. Maybe I should totaly remove the old kernel and mkinitrd..dunno if that will fix my prob. Ohh..I have rebooted after wards ... One strange thing is that I booted up with my old kernel and installed nvidia driver as well. To see if I could get my tv out back. At that point I had both drivers installed, maybe they did a conflict..I will reinstall all nvidia drivers including utils and only have beyond driver...I got a feeling that my driver mess things up totaly.

Satellite Pro M70: Can not get the TV OUT working

I have connected my laptop to my TV via the TV-OUT socket and a 4 pin S-Video lead. I have turned on the TV as an output in the advanced settings of my graphics card. I have selected TV via the Fn-F5 keys and I get nothing on my television.
Can anyone suggest what I might have left out to make this work?
The S-Video lead is new and the hook up to the TV is via a Joytech AV Control Center 2.
The Joytech unit is operational and the video lead appears OK as the Fn-F5 key press indicates that a TV is available - this disappears as an option if I unplug the video lead from the Joytech unit.
Any help would be greatly appreciated.

Hi Lorraine,
I presume that the TV is actually switched to your Joytech AV device ? I presume it gives some kind of signal so that you check that the TV can actually detect it. I once spent a happy few hours trying to use my TV in this way only to find it was switched to the composite inputs not the S-Video one. ;-)
regards,
