Disabling Legacy USB Support

Hi all,
I have a portable drive which connects to the system via a USB Y cable (with two male USB-A connectors - one draws power to aid the main one and give the drive extra power - both need to be plugged in). In OS X, it's recognized immediately after I boot up, but in Windows I must unplug both connectors and plug them back in before Windows will see it properly.
I spoke to SimpleTech/Hitatchi, the manufacturers, and they told me I needed to disable Legacy USB Support in my system's BIOS to fix the issue. Of course, Bootcamp doesn't have BIOS.
Is there any way I can do this?
All help is appreciated.

Make sure the burned DVD is good. As I found out (the hard way), there are a lot of bad DVDs out there.

If your DVD blanks are an off-brand, likely you are going to have a lot of trouble.
You might also have trouble if either your DVD writer or DVD reader are too old. I do not pretend to understand all the details, but it seems the "standards" have changed rather a lot, and you cannot take compatibility for granted.

Can a Mac Update disable a USB mobile broadband device?

Hi all,
Last night, my Clear internet went down on me, both home WiFi modem and plug-in USB mobile broaband device. One minute I was on the net and the next, not. After wasting 2 hours with Clear customer service, I gave up and started Googling and found some lovely folks here on Apple Support communities that suggested uninstalling Intego Virus Barrier X6. Well that worked to get my home WiFie modem up and running. But my MacBookPro (10.5.8) doesn't still see the USB device plugged in. It's not my USB port, as other devices work fine plugged into the same port.
I called Clear customer service back and they suggested that there is some phantom Mac Update that has disabled my USB device. I know they're bs-ing me. I think the device is broken. But I thought I"d see if any other Mac people have had a problems with a mobile Broadband device in connection with either Virus Barrier or Mac updates? I've googled lots of search terms and can find no one else with this complaint

No.
It is possible for the Mac (or another computer) to update the firmware of a device, but you would know if you did that. Likewise it is possible for the Mac to be unable to detect the device through its own fault - such as the Mac's USB ports or wifi failing. But the Mac's updates are only for the Apple hardware and software. Also, updates take effect immediately. Were you installing an update when your connection went down?
I think their tech support people are trying to get you off the line. If such a thing happened people would be reporting it all over the place, not just here. Ask them to point you to some reports. Ask which update did it.
Best of luck.

Ndiswrapper usb support

Is there a way to disable usb support in ndiswrapper ?
Edited:Forget it. I've compile it from the source.

Thanks for your reply, Phrodo_00.
I think it is using the correct ndiswrapper module (beyond).
Looking at the modinfo output:
$ modinfo ndiswrapper
filename: /lib/modules/2.6.16-beyond/misc/ndiswrapper.ko
license: GPL
version: 1.16
description: NDIS wrapper driver
Maybe this problem is related to the execution order of the commands (modprobe ndiswrapper, wpa_supplicant, dhcpcd) during boot.
Everything works fine after killing wpa_supplicant and restarting the network, the ndiswrapper module is loaded, wpa_suplicant is running as a daemon, etc.
$ ps -ef | grep wpa
root 4262 1 0 10:12 ? 00:00:00 wpa_supplicant -wB -i wlan0 -c /etc/wpa_supplicant.conf -D wext
$ ps -ef | grep dhcp
root 4274 1 0 10:12 ? 00:00:00 dhcpcd -t 30 -h portatil wlan0
$ lsmod | grep ndis

10.6.8 Update - No USB Support - Help!

Early 2008 MBP under warranty for another 34 days. Nothing interesting installed beyond usual Mac, MS and Adobe software. Occassionally run Parallels 6, but not today and not recently.
At 9:00 was offered the auto update to 10.6.8. Closed open apps and let the MBP do its thing.
On reboot the usual screen came up but there was no trackpad or keyboard support. Was able to use a bluetooth mouse and all apps opened but still unable to type anything or use the trackpad mouse. Also noted that there was no USB support for an external drive, or keyboard (or I would have tried to roll back to 10.6.7 with Time Machine.
Rebooted multiple times with the same outcome.
Spoke to Apple and they had no suggestions except to get warranty help. Well that's 50 miles away (service provider, not an Apple store). Any suggestions to save me two trips (there and back to deliver and pick it up)?

I have a early 2008 macbookpro 2.8 duel with silver keys.
I purchaed the 10.6 disk from the apple store. I've had the machine for years and purchased it refurbished from apple.
I did the erase and install and migrated everything over from external drive, then did update to 10.6.8 and the usb ports still would stop working after a few hours.. Then I read on another apple community forus to reset pram, and pull out the power cable, take out the battery and hold power key for 5 seconds, then restart. that seemed to fix usb issue so far..
But overall my computer seems to be running slower then when using just 10.5.8 and it did not wake from sleep once and I had to force power off and restart.. But maybe its just getting used to 10.6.8. we will see..
Also, on another note, my battery is totally dead, and I can only run computer with power cable.. Will this affect things? it never did with 10.5.8..
Oh, on my erase and install, I just did the simplest version and did not do the full erase to zero using he advanced security measures.. I just did the one where it writes on top of everything..

Debug mode - NATIVE_POPUP_LOV - Fallback to legacy LOV support.

Hi,
When I consult the debug logs of my pages, I see the rendering of my items.
Following the NATIVE_POPUP_LOV items, I see 2 processes.
1- Rewrite SQL to: ...
2- Fallback to legacy LOV support. Please check your SQL statement.
I have a question regarding the second process. What does it do? What do I have to modify in my SQL statement to avoid the "*Fallback to legacy LOV support*"?
Note: I am using the table function in my SQL statement.

Hi Patrick,
The LOV SQL statement is based on a table function. I am using aliases on my 2 columns. I can edit the page item without error. I didn't check the page with Advisor.
Example of the query:
select dimns_name d,
dimns_value r
from table(my_pkg.get_lov_dimns('param1','param2','param3','param4'))
When using table function to generate my data, I can't use the search functionnality of the popup lov item. The search returns zero rows. I went into the v$sqlarea table to make sure that my query is executed. And it is executed.
Thanks.

Cannot disable Acrobat PDF support in Safari

I want to disable Acrobat PDF support in Safari. I open Acrobat 8.0.1, go to Preferences>Internet, and uncheck "Display PDF in browser using Acrobat 8.0.1". I click OK.
However, when I quit Acrobat and Safari and re-opened Safari, Acrobat PDF was still enabled. I went back to Acrobat, opened up Preferences, and sure enough the "Display PDF in browser..." checkbox was checked again!
So I unchecked it once more and clicked OK to close Preferences. I figured I'd open Preferences once more to see if it worked - and to my amazement "Display PDF in browser..." was checked again!
It seems it is impossible for me to turn this off. Any ideas how I can disable this without uninstalling Acrobat?
I've tried going to Help>Repair Acrobat to disable the PDF plug-in, but it doesn't appear in the list. The only plug-in listed is the one for making PDF files from Microsoft Office applications.

Chris,
Go to HD/Library/Internet Plug-Ins/ and remove AdobePDFViewer.plugin.

Solaris 10 Oracle VDI VirtualBox 3.2 USB support

Dear folks,
This my first time to the forum, since we are in the progress of deploying 240+ thin clients using Oracle VDI. I was piloting the project in a desktop machines with Sunray 3i. I installed Solaris 10 9/10 and Oracle VDI 3.2.1. However, while I was creating WinXP VM in Virtualbox 3.2 -the one which came with Oracle VDI 3.2- I got that error about being unable to connect to USB proxy server. Eventually this error leads to that all my VMs doesn't support USB redirection. So USB flash disk drive doesn't work in my Sunray 3i. Reading VirtualBox documentation Installing on Solaris hosts , I came across this info "*This does not apply to Solaris 10 hosts due to lack of USB support.*" Is this real?
Does this mean I can't redirect USB hardware to my VMs in the server via Sunray 3i? If this is true, what is the workaround for this problem?
Please advise me. . .

Other than the documentation stating it doesn't work, in practice have you tested it to not work also?
We have two Solaris 10u5 machines running Vbox 3.2.12 and they pass through USB fine with our Sun Ray 3's (not 3i's but that shouldn't matter).
Did you enable USB passthrough in the VDI core by selecting the desktop pool and going to the Settings -> Sun Ray RDP Settings? Theres checkboxes to enable USB/smartcard pass through.

When I plug in an USB stick, my MacBook Air disables all USB devices

When I plug in an USB device, my MacBook Air disables all USB devices and the keyboard. It looks like it would freeze, but all applications still work. It just does not respond to neither keyboard nor mouse. The only solution is to force-restart it. What can I do? I am using Lion and have updated it. The same error occured with Snow Leopard as well. Unfortunately, it sometimes happens and sometimes not. I have a suspicion it is related to the devices power consumption in corelation with the battery charging status.
I am using a MacBook Air 13", late 2010 version.

Have you tried plugging the flash drive into a different Mac to see if it works? The Air shouldn't have any problem with it, I use a couple of flash drives in mine, although I don't have a pq1. Did you try both USB ports on the Air? Do you have another flash drive you can test in the Air, or a different USB device, like a hard drive or printer?
The only thing I can think of is either a bad flash drive, or a bad USB port on the Air. Sorry, can't be more help than that.

Java usb support for windows

Hello All
I do no know if this is the right place to post this topic, but does anyone know of an api that provides usb support for windows. I was looking a jusb, but the documentation says it only has support for linux. So far the best I have found is Mr Stahl's thesis which provides very limited support for windows. I was wondering if there was anything more stable (free or not)
Thanks

Hi,
Im trying to connect 2 computers using USB or Parallell port. On one computer I want to install a printer (regular windows printer) that prints through either USB or the Parallell port. On the other computer I want to listen on the Parallell port/USB port and receive the input and write it to a file.
Does anyone have a some sample code to do this? I've tried the following code (rxtx) but it cant find more than 2 ports (one parallel and one serial - no USBs even though I have 5 USB ports). Since I could only find the USB I tried to listen on the Parallell port. Problem is that I dont receive any data.
<---THE CODE--->
Enumeration port_list = gnu.io.CommPortIdentifier.getPortIdentifiers();
while (port_list.hasMoreElements ()) {
CommPortIdentifier port_id = (CommPortIdentifier)port_list.nextElement ();
          if(port_id.getPortType () == CommPortIdentifier.PORT_PARALLEL) {
               System.out.println("Found port "+port_id.getName()+ "id "+port_id);
               CommPort commPort = port_id.open("",2000);
               InputStream is = commPort.getInputStream();
               byte buffert[]=new byte[1024];
          int len;
          System.out.println(">>>>>>>>len "+is.read(buffert));
          while((len=is.read(buffert))==-1)
               Thread.sleep(500);
               is = commPort.getInputStream();
               System.out.println(">>>>>>>>len "+len);
}

Does VECTOR exist only for legacy code support??

My colleague informed me that the VECTOR class was a JAVA 1.0/1.1 implementaiton and is only still around for legacy code support in JAVA 2. Is that a valid statement?? Does SUN publish anything about this issue??

In JDK1.3 doc it says Arraylist is faster than Vector but unsynchronized. So I guess it's better off using Arraylist in most cases, but Vector is still more convenient to use to ensure threadsafe.

How can I disable my USB port?

I need to temporarly disable my USB ports on my powerbook.

For what reason ever..
IF this is possible then I would take a deep look at the developer tools. Inside the /Developer/Applications folder is a USB device tool ( designed to develop and test USB drivers/software ) .
Only other way would be geeky hacking on the open firmware prompt, but I don't know the aliases or command that would be needed. You will however need to digg very deep inside the technical side of a Macintosh and get an understanding how OF and the Hardware Abstraction layer in OS X works and maybe unload manually some critical kernel extensions on boot-time.
Good Luck.

[SOLVED] Virtualbox and USB Support

I use Virtualbox quite regularly for work and school. I have Windows installed within Virtualbox, and I use it whenever school or work requires. However, USB support has never worked for me (even with the fstab addition) and I thought maybe I'll spend some time to figure this out.
Basically, I may want to do things like insert a flash drive and make it available to the VM, or even sometimes an MP3 player or even my PSP. Unfortunately, it doesn't seem to work. There USB filters, but often times the device I want is greyed out, and can't be selected. When I am able to select a device to create a filter, it doesn't do anything. I did check the Wiki already.
Maybe I'm missing something? Or is USB support in Virtualbox just that bad? I was hoping there would be some sort of way I can dedicate a USB port to Virtualbox, and make it exclusive. I think VMWare can do that but I'm not sure that Virtualbox can.

I hope it's ok to post in this thread because if I started a new thread the title would be identical. I am also using virtualbox_bin from AUR and while USB passthrough works just fine to my Windows XP guest, it can't be working any faster than USB v1.1 speed. I have the appropriate entry in /etc/fstab and am a member of the virtualbox group. No permissions problems and from what I can tell there's no corruption of data to/from any of my USB flash drives. The only issue I've had other than the aforementioned lack of speed is with a 1TB Western Digital Passport. It seemed to have "lost" some directories. In other words they appeared completely empty on the XP side. After shutting down the guest I verified that all of the files were indeed still there and intact. I've basically chalked that one up to a deficiency in Windows XP. But this speed issue is seriously holding me back.

HP F4580 on Imac in windows 7 bootcamp, won't install "no usb support" works OK on Mac side

Trying to install my HP F4580 so I can print from the Windows partition on my iMac,. Downloaded and ran the drvier utility but it fails saying "this PC has no USB support". Whereas the printer works fine on the Mac side of the partition.
This question was solved.

Hi,
Although installing the printer on Windows by using Bootcamp may work, it is not guaranteed...
The windows OS actually being installed as a virtual envoirnment, which means your Windows OS is using your Mac OS USB drivers as the host, and not those intended for Windows.
Therefore it is not being recognized by the software.

USB Support in Hyper-V. Very Confused.

I am running Windows 8.1. I start Hyper-V and need to install which Operating Systems to have USB support inside of the VM? Is this possible? I tried windows 7 and I do not see Enhanced Session Mode. I tried windows 8.1 and again I do not see Enhanced
Session Mode. Is it possible to have USB access in a Hyper-V VM?

Hi Sir,
Client hyper-v needs the host OS is x64 win 8/8.1 Pro/Ent :
http://technet.microsoft.com/en-us/library/hh857623.aspx
Enhanced session mode comes with win8.1/server2012R2 , also the guest OS should be 2012R2/win8.1 :
