HP dv5 USB hang

Hi,
I have a dv5 notebook (dv5-1138nr) that was purchased shortly before Christmas. The computer is running Vista 64-bit.
About half of the time you plug anything into an external USB port, the computer simply locks up. Everything is frozen. The only way to fix this is to reboot the computer. This has happened with several memory sticks as well as a USB external mouse.
Any ideas on what might be causing this or how to fix it?
Thanks,
Mark

I'm having the same problem with my dv6-1259dx notebook. Hoped that Win 7 would help but did not. There is no bios updates but reinstalled it anyway with no results. This is a common problem on many different computer but I have never found a resolution.

W2k + usb = hang ?

For the life of me, I can't get USB working on my new PC. Whenever I plug in _ANY_ USB device, the PC hangs on me. Sometimes it starts working again, but my mouse or keyboard will stop working. My mouse and keyboard are both PS/2.
PC specs:
3.2 ghz P4 (NW)
MSI 875P Neo-FISR
512 mb 3200 DDR Crucial RAM
350w PSU
Old GF3 video card
1 hard drive
1 DVD-ROM
Bios setup:
USB Controller - Enabled
USB Device IDE Config: All Device
OS: W2k w/ SP4 (and _ALL_ other critical updates installed)
In System Devices I have the following listed:
- Intel(R) 82801EB USB Host Conroller (x4)
- Standard Enhanced PCI to USB Host Controller
- USB Root Hub (x4)
I also have the latest Intel Chipset drivers installed.
I verified all my USB devices in 2 other PCs. They work perfectly in those PCs.
I clicked the "Refresh USB drivers" link on my MSI cd after I installed SP4
Everything else is working perfectly except for this. Is my mobo defective? I'd hate to have to take it apart and send it back to newegg. I'm installing XP now just in case but I hope someone can give me other suggestions. Anyone?

Welp... I think I'm screwed. I Installed XP w/ SP1 and got the following messages:
Quote
"One of the USB attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message."
Of course, I can't click the message because my mouse and keyboard stop working.
Help please.

Booting From USB Hanging At Certain Point

Hi all, new to the forums as i want to give Arch a go if i can get past this hanging problem. I created a bootable USB drive using the command - # dd bs=4M if=/path/to/archlinux.iso of=/dev/sdx in a terminal. (obviously changed parts of it as necessary.
But when i boot from the USB it hangs at this point:
Arch Linux 3.9.4-1-ARCH (tty1)
arch iso Login: root (automatic login)
Root@archiso~# [OK] started initialized pacman keyring
[OK] Reached target multi-user system
I left it for over 30mins and still stuck at that point any thoughts on what could be the problem and any solutions.
currently running LMDE 15 cinnamon
Any help would be appreciated
thanks
EDIT: Didnt explain it enough i basically cant type in any commands it just hangs there

Did you validate the checksum of the ISO file that you downloaded? Does it boot and login successfully on another machine (if you have another to test it on)?

2013 MBP Mavericks/Bootcamp USB Hang

I have a Late 2013 MacBook Pro 15", 16gb, discrete graphics, etc. Of course I am running fully patched (as of today) OS X Mavericks, and I am also running boot camp with Windows 8.1.
During the POST the machine hangs if I have my USB hub connected. By "hang" I mean that the screen is just gray, the Apple logo never appears, and it can sit there as long as I let it, but it will never boot to either partition. If I remove the USB, allow it to get past POST and boot to either OS, then reconnect the USB hub, it recognizes it and all devices and we're off to the races. Devices connected include a keyboard, mouse, camera and printer. I've tried removing various ones to see if it changes, but it doesn't.... it will only boot if the USB aren't connected at all. I now welcome any thoughts and questions you may have on this issue.

If you have your /Home/Music/iTunes/ folder backed up with Time Machine, then you can restore the folder to the new computer using the Time Machine application.
Please visit Pondini's Time Machine FAQ for help with all things Time Machine. I believe you want Item 17.

USB hangs boot up

After installing drivers for my Canon MP170 I can't boot up with USB devices connected. At the moment I have an i-Rocks USB hub with a Sony Ericsson w960 and the MP170 connected to it.
During the boot up the white initial screen takes really long time to finnish and when it reaches the blue screen boot up halts. Removing the USB hub makes the white screen pop up for 2-5 seconds and then it continues the boot and boots up completely.
I'm guessing removing these drivers would solve the problem. However I'm not a very experienced mac-user and don't know where they are located.
If this problem can be resolved in any other way I'm open for suggestions.

The following details my procedure for removing the Canon PIXMA drivers.
1. Open System Preferences > Print & Fax. Highlight the Canon printer in the Printer list and click the minus ( - ) button.
2. Hold Control key and click in the empty Printers list. Click on Reset Printing System. Note that this will delete other printer queues if they exist.
3. Close Print & Fax
4. Go to Library > Printers > Canon and delete the contents of the BJPrinter folder.
5. Go to Library > Receipts and delete the Canon driver package file, if one exists. The file name will show Canon MP170 xxx.pkg
6. Go to Library > Preferences and delete the Canon folder.
7. Go to HD > Users > Shared > Canon and delete the BJPrinter folder if it exists.
8. Empty the Trash
With the driver files removed restart the Mac and see if the problem still exists with the MP170 connected via USB.

Install Windows XP on external USB drive - MSI 915P

I have a MSI 915P motherboard and i am trying to install Windows XP on my external USB hard drive. Everything is fine installing Windows XP but when it says to reboot the USB drive does not boot. Any help please?

BIOS is set to boot from USB device. It shows Windows XP Home Edition on my internal drive and XP Professional on my USB drive. Internal boots but USB hangs with a dark screen... ??? ??? ???

No usb in lion

Just installed Lion. When the system is on for a while, the screen blanks, and everything is dead. Computer is on, I hear the drives being accessed, iTunes is still playing, but I CANNOT ACCESS ANYTHING. USB HANGS. I can only to a hard restart with the power button. HELP!!!!!

Maybe you have a bad USB cable or device or driver.
Try command + r on startup and repair the drive

Generation gap - firewire/USB

Ok, so I just got my 8gig Nano - Woohoo!
Also just found out that I can't sync it using my 3gen dock via Firewire - Boo!
Here're the questions:
The dock connectors on the new Nano & 3rd gen iPod are the same, correct?
Can I just swap the cables and plug my 3rd gen dock into USB?
The big question:
Can I sync (& charge) my 3rd gen iPod via USB?
It won't bother me much if I can't use the old dock anymore, but it will bother me if I have to have 2 cables (1 FW & 1 USB) hanging out of the back of my Mac to charge the 2 different generations.
Thanks in advance!
-Dennis

Thanks Niel,
How do I determine if I have USB 2.0?
It's not specified in the system profiler or the specs listed here:
http://support.apple.com/specs/powermac/PowerMac_G4_DigitalAudio.html
Do you know whether or not my 3rd gen dock is interchangeable between generations and FW/USB?

Multiple serial ports streaming - BSOD/freezes - Hardware or Software problem?

Hello all,
I just joined the forums as I'm in dire need of some help with LV. I'm trying to hook up three lasers for an experiment. These are connected to my laptop via seperate RS232 cables with an adapter each to a COM port. I found an LV example that reads in one laser from the manufacturers site (something with .dll files and a C++ library). I'm a beginner with LV and I can't really say I have experience, especially not with custom libraries, so I just tried to make it work somehow. So what I did was basically copy it three times and reconnected some wires and changed the output format. I've added my program to this post; warning, you might get slightly sick by looking at it.
Anyway, my main problem is; it works, but only for a limited time. After some time the VI will crash or my laptop will BSOD. Now, since my VI isn't very professional and probably has a very bad structure I'm not sure whether this is a problem with the VI or with the RS232 adapters/USB hub. I read some things on faulty RS232 adapters that conflict, but I can also imagine my VI can't deal with three data streams correctly, so I'm not sure where this is coming from.
I was hoping that if any of you would take a glance at my VI, you could tell me whether it's my VI or not. I'd rather confirm this before I buy three new RS232 adapters.
P.S. I'm running this on LV 2011 and LV 8.2.1 (my laptop with 2011 only recognises 2 COM ports simultaenously and my other laptop with 8.2.1 all three, but my laptop with 2011 can handle the crashes better)
Thanks!

As an off the wall suggestion, check the usb "power save settings" under "control Panelower Options:Edit Plan Settings:Advanced Settings:USB settings" You want the USB selective suspend setting to be Disabled. Another possible idagnostic tool might be to do a Power Efficiency Diagnostics Report which we have found has occasionally pointed us to usb hanging issues.
Using the same type usb-serial adapters doesn't guarantee anything, but I have run into issues where a vendor's driver was implemented incorrectly. It ended up being a wrapper around the FTDI driver, and the wrapper dll wasn't correctly made multi-threaded safe. I browbeat the vendor (I was working at a LARGE corporation, with a prospective LARGE purchase of the devices) into telling me what calls their wrapper made. I then used the FTDI dll directly, not using the "simplified interface" of the vendor's dll. FTDI's dll was thread safe, no more random lockups/BSOD.
Good Luck, these are incredibly painful!

Partitioning External HD Failed!

New iMac, trying to use existing external HD (newertech 150GB) as a Time Machine backup (yeah, I realize now it's too small), was attempting to partition it to GUID Partition Table, as recommended somewhere else in support. It failed (input/output error) and now the HD isn't available at all. It shows up in Disk Utility, but not it's subname (and the drive doesn't appear on my desktop), and it isn't available for either First Aid, and partitioning attempts continue to fail. I restarted, unhooked all the other USBs hanging off the drive, and have it connected via Firewire and USB. Can I get this drive back to use in any form? Thanks.

Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

H67MA-ED55 (B3) Error 98

Hello,
I keep getting this error - 98 code on my bottom-right corner and I have to manually restart the PC.
My other specs: i5 2500k with Prolimatech Samuel 17 (no OC), 2 x 2GB Corsair 1333Mhz dual-channel, MSI GT440 Low profile, S-ATA TSS DVD-RW, Seagate 320GB S-ATA 3Gpbs, Seasonic 430W.
Sometimes I hear 1 beep (I read that it's good). I'm using Windows 7 Ultimate x64 and I upgraded from onboard video to GT440.
If you have ideas or suggestions I thank you in advance!

if im not mistaken that error 98 is caused by legasy usb hang durin boot up!
only fix is to disable legasy boot up on your computer n bios and the hang should go away (one word of caution - get a PS/2 keyboard if you need to be able to use inputs durin boot up before you OS loads as disabling legasy usb boot up will lockout the usb ports before The OS is on)!

RxtxSerial library multiple serial ports listener

Hello All,
I am using rxtxSerial library (import gnu.io.*; compatible with previousely available from Sun import javax.comm.*;) for my bridge application. Th example provided in the library's web site with nulltest.java employs only one serial port. It is powerful since it is threaded and detects incomming/outgoing streams.
However, I would like to bridge between servers so multiple ports will be employed. Do you heave any suggestion how to obtain multiple port handling (reading/writing) within the same class. The null test code is presented as follows. Simplest idea is to use arrays, but more details are required.

New MBP comes with Mavericks - Upgrade vs Clean Install of Yosemite at this point?

Bought a New 13" MBP today from my local Apple Store. It came with Mavericks instead of Yosemite. I realize there is probably a lot of advantages to doing a clean install of any OS, especially when you have a lot of usage on it which creates files all over. However, I'm wondering if that advantage is minimized by doing an upgrade with a pristine OS. If very few, if any, files are left behind from Mavericks that are no longer needed does it matter?
Obviously upgrading saves me from having to go through the hassle of creating a bootable USB (wherever that thing is in one of the many junk drawers).

If it were I, I would just di a clean install if you have not configured it already...it's good to have a bootable USB hanging around just in case. It's easy to make one in Terminal if you have at least an eight (8) GB available with this (I just finished one):
sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Yosemite.app --nointeraction

Hangs using USB connections

Hi,
what do you explain it seems to be almost the same as mi case.
iMAC with anything conected : no problems.
All tests, onyx,.....all OK!
If I conect my scanner and/or my USB_extHD and/or my HP laserjet .... then in any moment my iMAC hangs on color circle and it has to be stopped with rear button.
log:
[0x6a56600] The IOUSBFamily was not able to enumerate a device.
4648.870 [0x6a56600] The IOUSBFamily is having trouble enumerating a USB device that has been plugged in. It will keep retrying. (Port 3 of hub @ location: 0xfd100000)
what it means?
It's a new 5 months iMAC!!
I'm trying to understand what happens. Could anyone help me please??
Thank you.

Hello azimut and welcome to Apple Discussions
Sounds like either a bad device, a bad USB cord or there something wrong with the way you have the devices connected. Can you give us a little better description of how you have everything plugged in, we can only imagine how you have all those devices connected up to the three ports on the back of your iMac.
Try connecting things up to the three Ports this way:
Port 1: Keyboard with only the Mouse connected to Keyboard.
Port 2: The External HD
Port 3: A Mac Compatible Powered Hub (examples below) to connect the printer, scanner and any other USB devices into.
Examples of Mac compatible Hubs:

USB modem and Internet Sharing causes system to hang.

First my setup. I have a Mac mini (early 2009) running 10.7.2 connected to the Internet using a Sony Ericsson W910 as a USB modem. I am using Internet sharing via Ethernet to a 1st generation (n) AirPort Extreme to give Wi-Fi to other devices (iPhone, Xbox 360, PS3 etc).
Now the problem: When Internet Sharing is on regardless of what interfaces are used (Ethernet, Wi-Fi, Bluetooth PAN etc) eventually—that word is key—my system will hang. Internet will be unavailable to every device and my Mac itself (but they will still be connected to Wi-Fi) and any app that is running willbeachball. Any app I launch—or try to—will also beachball. I've tried leaving it to see if it will resolve itself —even overnight—but it always requires a hard reset.
The eventually part. I haven't figured out what causes this but I have an idea which I'll explain later. The times this happens is totally random. It has gone days with no problems and other times has happened minutes apart. Usually it's about every 12-24 hours.
It's definitely Internet Sharing which is causing this because when I turn it off I don't have any problems. I've tried every configuration. Only sharing via my mini's Wi-Fi or Ethernet, leaving the AirPort out etc. As soon as I turn on Internet Sharing I've started a countdown to a hang.
On inspecting the Console the last messages before a hang without fail are always:
12/12/2011 06:31:07.000 kernel: 80 80 AppleUSBCDCECMData: getOutputBuffer - Output buffer pool empty
12/12/2011 06:31:07.000 kernel: 80 66 AppleUSBCDCECMData: USBTransmitPacket - Output buffer unavailable
12/12/2011 06:58:58.312 com.apple.usbmuxd: _handle_timer Fish out of water!!!
Repeated hundreds of times. Quick Googling indicates that AppleUSBCDCECMData is a USB driver. Apparently I have version 4.1.15 which appears to be the latest.
I'm aware this is a rare configuration but I believe it affects every USB not just this particular phone.
Is anybody else experiencing this or knows a way to fix it?
Thanks.

Thanks Barry.
The hub is on its way to the manufacturer for after sales service...
But the issue with AirPort remains the same, even after resetting SMC.
Some clarification:
* It happens just after computer wakes up from sleep. Restarting solves the problem and the issue doesn't arise until computer goes standby again.
* The whole WiFi card becomes unresponsive. It is not only the Turn Off button, but the whole functionality is stopped. The card can not be activated/deactivated and it doesn't connect to any network. If it is used for internet sharing, clients are unable to connect.
