Issues with Sandisk U3 2GB USB Thumbdrive

My MBP has 2 USB slots, when i plug in my U3 into any of the slots, the drive is recognised by MBP. But if i were to transfer files (usually happens to large files such as those 50MB and above) from U3 to MBP, the transfer status just hang and i cannot eject the drive. So must force it to quite by manually unplugging the U3.
Then i would normally plug it in again for few times and i can transfer the files. This does not happend when transfer frm MBP to U3. And this does not happen to other my other Sandisk Cruzer 1GB thumbdrive.
From what i observed if i plug in the drive long enough (let say 5 min) then only initiate file transfer from U3 to MBP, usually it will not fail.
BTW, using the same U3 on Windows does not give any issue. And i've formatted my U3 a few times as FAT32 format.
The following is the error log:

Hope someone can help on this.

Will try the ignore ownership thing later this evening. But doing so does not have impact on the existing files in the U3 rite?
Sorry as I do not understand how does OWNERSHIP works in this case.

  • Are there any known issue with the HP 3005pr USB 3 replicator ?

    Hi,
    I recently ordered an HP laptop Pavilion dv6t-7000 with Intel i7 and nVidia video. While the unit isn't due to arrve for about 2 weeks, I'm looking for a docking station/port replicator.
    Are there any known issues with the HP 3005pr USB 3 replicator ? Does it fully support Win7 64 bit? I am also considering the Targa U3 unit, but I'd prefer HP if I can be assured that it works.
    I'd like to be able to leave the laptop closed when at my desk so I can use  an external keyboard, mouse, and monitor.
    Does HP make this device or does a 3rd party make it for them?
    I've read so many stories on various forums regarding these things.
    Any suggestions from HP or others? I need to order something soon, but I don't want head aches when it arrives.
    thanks,
    Steve

    This HP USB 3.0 Port Replicator fully supports with Windows 7 64-bit, if that is the one that you are talking about.

  • MacBook Pro Retina Late 2013 Compatibility issue with Bose Companion 5 USB Speakers on Mavericks

    Hi, I wonder if somebody has compatibility issues of new MacBook Pro Retina (late 2013) and Bose Companion 5 USB speakers? They work fine on a left USB port on my MacBook Pro, but doesn't work at all on a right one: USB speakers are not recognised or if recognised as "Uknown Audio Device", they doesn't work any way and iTunes stops playing till I take USB cable out.
    I tested them already on two identical machines - the same issue: left USB port works fine, right one - not.
    While comparing, I tested this audio device also with other MacBooks:
    MacBook Pro 15" 2008 (Mavericks) - both USB ports work fine
    MacBook 13" 2010 (Mountain Lion) - both USB ports work fine
    MacBook Pro 13" Retina early 2013 (Mavericks) - both USB ports work fine
    So it is somehow related exactly to the MacBook Pro Retina 15" Retina late 2013 with Maverics. I guess some sound card and USB port communication issue. Does any body exeriences such problems as well?

  • Issues with i-Phone4 car USB Connection since IOS5 Upgrade

    Hi,
    I connect my i-phone 4 via Bluetooth to my car, and also plug it in via USB, so that I can control the device using my steering wheel controls.
    Since ugrading to IOS 5, the Bluetooth phone connection appears to be working OK, but my music cuts out after a minute or so, although I can still select music via the car controls after it cuts out, but it won't actually play.
    If I look at the screen of the device itself when the music is playing, the screen tells me that it is connected to an accessory, and when I click on the device option at the bottom of the screen, it gives me two options for the connectivity - "USB" or 'My Volvo Car' (and the option selected is "USB").
    However, when the music cuts off, if I view the same screen, it has switched to 'My Volvo Car'.
    The same thing happens when connecting via the AUX input. The music cuts out after a minute or so, and it swpas to the default of 'My Volvo Car' so I can't hear the music again.
    All of this worked perfectly until the IOS upgrade, so any help or advice to resolve this issue would be greatly appreciated !
    FYI - I have a 2011 latest model Volvo XC60 R-Design with the Premium Stereo.
    Thanks !

    Hi,
    Not exactly
    The only compromise I have found is to also stream the music via Bluetooth too (select 'Bluetooth' in the 'Input Menu' of the car, instead of Aux or USB).
    It's very impressive for new passengers (like when you first stream music from your i-Phone to your stereo at home using Airport Express), but the only downside is that whilst you can change tracks within the same playlist via the steering wheel controls, you can't hunt through menus any more with the scroll wheel 
    Not a perfect solution, but better than nothing
    Please let me know how you get on and whether you find something better !

  • Measurement Computing USB-DIO96H driver issue with Labview 2012 SP1 on Windows 7 x64

    Is anyone else having issues with measuremetn Computing's USB-DIO96H driver in Labview 2012 SP1. It throws warnings in Labview when loaded that are unresolvable as you can't save to the DLL driver file. Also it regularily crashes Labview randomly. I am not impressed with their driver. Anyone have any suggestion other than replacing with NI-DAQ solution, which I am working on?

    I've taken a look and I don't see any drivers available for that device on ni.com. There are two potential workarounds that would both involve building your own driver:
    1. Write a LabVIEW application that calls functions on the DLL you downloaded from Measurements Group
    2. Write a LabVIEW application that addresses the device using NI-VISA and serial communication.
    Some resources if you choose to go down that path:

  • Samsung Fascinate, problems with playing music via USB port on car stereo

    Before the update, I could play the music files on my Fascinate via the USB port on my Kenwood stereo, and control basic functions such as skip, pause etc.  Now, my stereo does not recognize the device, and cannot read the files.  I went to local Verizon store where a sales rep tried to connect it in here new Kia Soul and it didn't recognize the device either. It will play via the AUX jack, but I lose player control and the phone does not charge via the AUX cable.  She did a hard reset which did not resolve the problem.  We tried one of the other employee's Fascinate in my car, which did not work either.
    So, after hoping to be able to stream music via Pandora, Jango etc thru the USB port after the update, now it seems its primary function is for charging.
    Also, the ALL SHARE function, which I used to get the music on my phone originally, does not work now.
    Anyone else have this issue with music player and USB connection?

    txgopher- I have personally never used my Fascinate to listen to music via USB via stereo however, I can see why it would be frustrating for you to no longer be able to do so when it was never an issue prior to the update.
    It sounds as though you and the store rep already did some troubleshooting by trying to duplicate the problem with another car, stereo and even doing the final troubleshooting step which is a master reset.
    Since you have done all of the necessary troubleshooting steps to no avail, it most definitely appears as though the software update has interfered with that USB connection in some way.
    What I have done is forwarded the information you have provided to Samsung in order for them to look into this concern as well as come up with a way to get this resolved.
    Please stay tuned because as soon as we hear back from Samsung we will be sure to update this forum with the results/findings.

  • IPhone Issues with USB Connection and Bluetooth in GM cars

    I recently purchased a 2009 Chevy Cobalt SS/TC and it has a USB connection for an iPod. Prior to the 2.1 updated the USB connection worked flawless as well did my handsfree/bluetooth. I had the Apple Genius Bar check my iPhone for any issues due to a corrupt update but everything turned up fine. When i connect to my car I receive an error message (iPod Did Not Authenticate. Check iPod Version). Also my bluetooth will sync but when you answer the phone using hands free you get no audio from the iPhone or speakers in the car. I used a friends iPod and everything worked fine but when I connect with a new iPod it displays the same error. I have contacted GM but they said talk to Apple.
    If anyone can help please let me know.
    Thanks

    Hey J,
    Well you got me thinking about your question, and I guess I didn't get it the first time. Again, I own the same car - 09 Chevy Cobalt SS/TC, Black. A lot of fun! I plugged my iPhone into the radio USB connection and get the same error. The GM radio does not support the iPhone. It will not authenticate. The GM radios' firmware is looking for an iPod, not an iPhone. That is expected. As far as the iPhone and it's Bluetooth, again the iPhone's Bluetooth hands free works fine, except I cannot answer the iPhone during an incoming call without first unlocking the iPhone then pressing the mute button on the steering wheel. For what it's worth the iPhone will charge through the USB connection. I'm a little confused on what you are trying to connect. Bottom line, an iPod should always work, an iPhone, not at all. Lastly, I have purchased the GM Personal Audio Link (PAL) and hope to use it with my iPod so I can put the iPod in the glove compartment. Although I have heard a lot of negative comments and issues with it for being slow and sluggish. If so, I'll be sending it back and I'll stay with the USB connection. I'll let you know how that works.

  • Connectivity Issues with USB 3 ports on macbook pro

    Hi,  I have a zoom r24 which is no longer working as an audio interface with my new macbook pro.  I have read a lot about issues with USB 2 devices not being compatible with USB 3 ports on the macs. This seems to be midi as well as audio devices.  Can anyone recommend or point me to a list of supported devices for both audio and midi which are guaranteed to work with a late 2013 macbook pro retina display.  I cant afford a thunderbolt device.  Thanks steve

    Just a wild thought here, but have you tried inserting a powered USB 2.0 hub between the MacBook and the interface?

  • Z87-G65 power issue with usb(port reset failed)

    All,
    I'm having an issue with my motherboard and wanted to see if anyone had suggestions.  In windows 8.1 if I have my webcam or external hard drive plugged in USB.  I get this error the the USB device is not recognized and the port reset failed(code 43).  I noticed when I turn on the PC and it's booting the light on the webcam and hard drive flash like it's not drawing enough power to stay on.  The boot sticks at 9c on the screen and I have to reset.  When windows boots they turn off.    Since it's before windows boots I think this is either a MB issue or a power supply issue.  I have a corsair 750 watt power supply so plenty of power.  Any ideas?

  • ThinkPad USB Keyboard with TrackPoint issues with scroll (55Y9003)

    Hi Guys,
    I am having issues with this  keyboard...
    I ordered it to use it  on my work where I have Dell Vostro desktops.
    However scroll simply doesn't work in all programs and even stops working ... I also using VM and it doesn't work at all in VMWARE even if you point inside it it still operates at host system !? Weird...
    I have installed latest drivers 1.01 but nothing... So when I removed all drivers and just keep default scroll work as default but still not in all programs and not in VM Ware, etc... Just to be clear my regular mouse scroll works in all and works properly...
    Is it possible that this keyboard will work only on Thinkpads used as external keyboard ?
    There are two things to be installed when I start a disk one is driver and second one is some interface driver which can be only installed on Thinkpads ?! Couldn't be that that thing is missing when running on non Thinkpad systems?
    Any help how to make scroll work in all programs?
    Thanks.
    Moderator edit: Removed UltraNav from the title. This keyboard just has a TrackPoint.

    I have the ThinkPad USB keyboard on a non-Lenovo desktop, and it works.
    Yes the keyboard driver installs, but not the Lenovo System Interface Driver, for obvious reasons. All the buttons and TrackPoint work.
    Yes the TrackPoint does not scroll in all programs. Search the community for "trackpoint scroll fix" and you will come up with instructions on how to fix this.
    I don't work for Lenovo. I'm a crazy volunteer!

  • Thinkpad X1 Mouse Issues with USB 3.0 Dock and WIndows 8.1

    I have a new X1 (3444-CUU) that I recently upgraded to Windows 8.1. When I connected to the Thinkpad USB 3.0 Dock, there was an automatic updated of the firmware on the docking station.
    Everything seems to be working except issues with my Keyboard and Mouse.Periodically, the mouse will disappear of the keyboard will simply stop working. Most recently, it was as if the delete key was stuck causing it to delete all my email (actually a feature I liked but unfortunately, can't allow).
    Is there a known issue with wireless keyboard?

    I have a possibly similar issue that seems to be related to the keyboard dock. In my case this is with logitec unified receiver, but what I found may help you narrow the issue's root cause.
    I found that after a reboot, the dock's USB ports (bothh SS or USB 3.0) will not recognize logitech's unified receiver. Even though it is Windows reporting it, it seems to be related to the hardware. What I do to have minimally invasive 'functioning' system is to undock the Helix (use as tablet). This makes the genuine USB 2.0 port of the tablet accessible. I then plug the receiver into that port and wait until the mouse is recognized. Then remove the receiver, re-dock the tablet on the keyboard dock and plug the receiver into the dock's usb 3.0 port. Then everything works.
    That seems to somehow circumvent part of the refreshing of the USB connected devices and allows them to work correctly.
    I wonder if that addresses your issue. Of course I am opening another thread and ticket with that issue (will post a link after that)

  • USB 2.0 issue with sleep mode--help!

    hey there,
    so i've searched this forum's board and found that it seems quite a few people have had issues with USB 2.0 and sleep mode on the mac. most of what i read, however, comes from people not being able to put the computer to sleep once new USB 2.0 cards or devices are installed. that is not the problemm I seem to be having, but is this:
    I recently purchased a Belkin USB 2.0 PCI card, and installed it on my MAC G4 tower. It seemed to work ok for a little while, but then i noticed that AFTER i put the computer to sleep, when it 'awakens' from slumber, it no longer reads the USB devices. if the device was plugged in prior to sleep mode, it sometimes reads ok. but if I try and plug in a new USB device, such as an iPod or flash drive, no dice. it doesn't mount on the Mac.
    I called Belkin tech support, and they were very helpful, but told me that the macs have had issues powering the USB PCI card once the computer is in sleep mode. they even directed me to an apple support page that has downloads that seem to address this, but they're for 10.0-10.0.4. I don't want to download that onto my mac (10.3.9) cuz im worried it might screw something up on my OS.
    I would LOVE a download link for a software updater for this if someone knows where it is, otherwise, I may have to return this thing to Belkin and go with a more mac-friendly brand. so im open to that possibility, too.
    any help would be GREATLY appreciated!!
    cheers,

    I would either complain to Belkin for a fix if there is one or return the card and try a different one. You should not have the problem, but Belkin USB hubs and cards appear to have more problems like yours than other manufacturers' products.
    You might try Sonnet's Tango FW400/USB 2.0 multi-card, for example, or Firewire Direct's 6-port FW800/USB 2.0 card.

  • FSCK and reboot issues with external USB drive

    I'm having an issue with an external USB hard drive I'm using.  I've always had issues with this drive cause my reboot to "freeze" when it's mounted.  Basically the system message with be sent out, but it doesn't actually proceed with the reboot.  No switch to init 6 or anything, but the shutdown process is still active.  I can continue to use the computer as usual, but I can't cancel the existing shutdown or try to enter init level 6 by hand.  So I just got around this by unmounting the drive before I shutdown.  However, lately when I try to unmount the drive I get an error saying that the drive is in use and I should check to see what processes are using it by runing lsof or fuser. 
    Yesterday I tried copying dsome files from the drive but there wasn't and activity on the drive. cp didn't report any errors though, it just sat there and did nothing.  I tried running fsck on the drive, but didn't get much farther.  I'll see some activity on the drive for about a second, then all activity stops and fsck just sits there. When I try to kill fsck, it won't.  Even with a kill -9. 
    I'm really confused as to what is going on.  Has anyone else had this problem?  Anyone have any ideas what could be causing all this or what I can do to stop this?  Thanks in advance!

    Press the reset button on the device. It is located between the USB and power ports. Make sure to take-out the external USB drive before you reset the device. Or you can also restore the defaults by accessing the Administration tab > Factory Defaults sub-tab in the router’s web-based setup page. Check out this link for the set up; http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=32cffead811249aea7e9fc6730bf59ad_KB25681_EN_v1.xml...
