How to detect a USB cable's speed rating?

The iMac is USB 3 compatible, I know. I also know that there are no USB 3 cable available yet, but I want to use USB 2, rather than a USB1 cable. I have a bunch of those cables, so I don't want to go out and buy a new one in a box marked USB 2. How do I VISUALLY detect which cable is a USB 2-compatible, and which is 1?

There are plenty of USB3 cables available, and USB3 cables are compatible with USB2, USB1.1 and USB1.
Here's one of many:

How to detect the serial cable been unplugged

Hi all,
I wrote a small application using the javax.comm api to talk to an external device. I would like to know how to detect if the cable is unplugged. Right now, if I run the application with cable not connected, if i start communicate with the device, the program will hang.
The program works fine with connection is there.
Please help me.

there are ways that do what he wants to do (though not what he says he wants to do), but they need to be implemented in hardware.
You could monitor the voltage on some of the pins on the serial connection for example, which tells you whether there's a signal on the line.
That of course would not detect whether the cable is there, as it has preconditions. It detects whether there's a signal on the cable, which requires that the systems on both ends of the cable are powered up and that the cable itself is not faulty.

First of all, Apple must learn how to design a USB Cable

Is this is the way you design an USB Cable?
it got damaged near the lightning connector, i bought a new genuine cable again 2 months before.
Again it got damaged in the same place.
P.S: Learn from school boys how to design an USB cable which can sustain for years.

I had one I kept accidentally slamming in a desk drawer. Never seemed to do it any harm. I did break a Belkin car charger by closing it in a car door but you can hardly blame Apple (or Belkin) for that. I still have Firewire cables from my first iPod, and more 30-pin connector cables than I care to think about. I don't recall any of my Apple cables ever going bad. And, frankly, I'm less careful than I know I should be.
I baby my iDevices, but I'm not very nice to my cables. No, I'm not. And yet, still never had an Apple cable go bad on me. I lost an iPad charger (left in a hotel room), which I cursed, but that was my fault, not the cables fault.

How to replace an USB cable?

I am trying to replace an USB cable for my iPhone 4 online, but there are only 8 options and none of them is USB cable:
Adapter, TTY, iPhone
Cable, AV, Component
Cable, AV, Composite
Earphones with Remote and Mic-US/L.A./Europe/Asia
In-Ear Headphones with Remote and Mic
Nike+ Shoe Sensor
Power Adapter w/ Plug, Ultra Compact, USB, iPhone/iPod-CAN
Power Adapter, USB, iPhone/iPod, 45x45-CAN
There is the power adapter and the headphone, but I don't see an option for USB cable. Any idea?

You can:
Use online resources: http://www.apple.com/support/iphone
or visit an Apple Retail Store: http://www.apple.com/retail
or call 1-800-MY-IPHONE (1-800-694-7466) (if you live in the U.S.)
Anyway, if you purchased the phone elsewhere, you need call the store support line for details on how correctly handle your request.

How to remove the usb cable

I just bought an ipad but I have to use real force to remove the usb cable.
I find nothing in de user guide about this.
Is this normal?

Yes. It will loosen with time.
A very slight left/right wiggle (not up/down) whilst pulling may help.

How do I see what (cabled) link speed I have between base stations?

Hi
I do own one new Airport Extreme base station and one older Airport Extreme (flat one).
Both are capable of 1 Gbit-speed via ethernet cable. I have the new base station as "master" and the old as extender (via cable). How can I ensure that the speed between them are using Gbit and not 100 Mbit?
"use cable xxxx" is not an answer I will settle with, I want to se the numbers somehow, via Airport Utility or 3rd party.
Is this possible?
Very thankful for any help I might get.
/Erik

There is no info in the airport utility and there is no third party to get you in either..
There is no easy way.. but a gigabit switch plugged in between the two devices would instantly show you the connection speed if it has LED indicators that show gigabit.
Gigabit switches are not that much money to payout now. Particulary if you have some place you might use one.
Otherwise simply do a throughput test.. plug a computer into the main unit by ethernet and plug another computer into the other end.. if you get a file copy speed say 15MB/s you have gigabit. You cannot pass files at greater than about 12MB/s on 100mbit.

LG mobile Phone not detected with USB cable!

What should i do?
My new LG KG810 Mobile does not Sync with my mac. are there some hacks available?

BitPim supports many LG phones but not the Chocolate.
Given the poor support for Macs in Mobile Phones you really need to buy a phone on the iSync list if you intend to use it as such.

How to detect USB Flash Drive name in LabVIEW

Hi there
I was looking for how to detect a USB Flash Drive name in Labview
appearently every time i insert USB Flash Drive in a computer, windows assign it a different name
once "J:" and sometimes "M:"
Is there anyway to obtain USB Flash Drive name programmatically in Labview ?
Because in my program an user shouldn't be able to access HDD Drives except his USB Flash Drive (for inserting some file ...)
thank you and excuse me for my poor english

I was able to get the demo.vi to load, but it could not load the other two because there is no block diagram associated with those. I'm not sure why this is. I haven't had any issues with other llbs before.

Can I detect USB cable unplugged for USB 6229

I am using a USB 6229 to control a moving machine. As a safety mechanism, I would like to be able to detect if the USB cable becomes unplugged and stop the machine.
I thought maybe I could use the Watchdog functions in DAQmx to achieve this, but I get an error which says that watchdogs are not supported on the 6229. Does anyone know if there is a way to detect the USB cable is unplugged on the 'machine' side of the 6229, please? I could build my own watchdog timer and control it using digital I/O lines, but I wondered if I was missing something obvious?
Thanks,
Paul

Hi Paul,
I don't believe you'll be able to do set this up with your USB 6229. There aren't any safety features like watchdog timers on that device and I don't believe there's a signal or anything generated when the USB cable is unplugged. Your best bet would be to build your own watch dog timer or perhaps look at a DIO device with this functionality built in.

Can I back up by using USB cable?

I have a Macbook, i used to back up via internet, but my internet shut down recently, I can't connect any internet at my place. So, can I still use airport to do the backup? and how? maybe the USB cable can work?
Thank you!

You do not need an Internet connection to perform a Time Machine backup from your MacBook Pro to an Apple Time Capsule or 802.11ac AirPort Extreme base station. Your MBP just needs either a Wi-Fi or Ethernet connection to that base station.

USB Cable for power only?

Hey everyone,
I want to be able to use the USB cable to provide power to my Ipod, but not install Itunes. Here is the situation:
I have a set of desktop speakers at work and I like to plug my Ipod into them to listen during the day. Of course over time my Ipod battery dies and I need to recharge it. So I need to stop listening to music and plug the Ipod in b/c I can't seem to figure out how to get the USB cable to provide only power to the Ipod. The screen says "Do Not Disconnect" and won't let me operate the Ipod. Now it is my company computer and do not (and can't) install Itunes. Is there a way for me to get the USB cable to only provide power and still operate my Ipod. Yes, I could shell out the cash for another power adapter or one of those docking stations, but there must be an easier way.
So desired end state is: Ipod plugged into computer (with no Itunes) being charged and listening to music over the desktop speakers. Any ideas??

Hi Raife!
First off, when it says "Do Not Disconnect" it is charging, but no, it won't let you fuction on it.
Try this:
Connect your iPod the computer.
When it says "Do Not Disconnect" on the screen, try resetting it: hold the "menu" and center buttons together for about 7 seconds. The Apple logo should appear for a few seconds before returning to a normal screen.
In this state, your iPod will be charging from your computer's USB port, but not displaying "Do Not Disconnect".
Note that when your iPod is completely dead and has no battery, it may have to charge while asleep/dead for about a minute or two before you can reset it or operatte it while connected.
Or, you can eject your iPod (you don't need iTunes):
In the bottom-right corner of your screen (with the System icons), there will be an icon that is a grey rectangle with a green arrow floating over it, representing the "Safely Remove Hardware" program.
Open it, and stop the "IPOD" process.
I hope this helps you,

How can I tether my Blackberry over USB cable (to sync info)? [SOLVED]

Firstly, I have to thank all of you for making this such a great community and excellent guide to getting almost anything working on Linux - this is what makes Archlinux the best distro IMHO. I have hardly ever needed to post anything here because the answers are almost always either in the wiki or the forums.
Lately though, I received a Blackberry 8310 and wanted to tether it to use its data plan here in Ecuador. After following http://wiki.archlinux.org/index.php/Blu … GPRS_Howto using a small USB bluetooth adaptor, this has worked well and the connection stays up nicely, though very slow (to be expected). Blueman is a great program! Looking at improving my connection speeds (and reducing my latency), I am now trying to get the phone tethered via a USB cable to the phone, rather than over-the-air (Bluetooth).
The problem I am having is that I cannot establish which device exactly is the USB port connecting to? Before this phone, this worked fine on my Nokia E51 setting the modem to be /dev/ACM0. On Nokia, I would connect the phone, select PCSuite mode and 'sudo wvdial movistar' or my /etc/ppp/peers/movistar script would work fine. Blackberry however is a whole different kind of animal. I connect it with a standard USB cable, select 'no' to mass-storage-mode on the phone, and can see it in lsusb fine but the only device I seem to be able to use is /dev/tty2 but modem not initialising.
How can I be certain which device I am using? Will post some lsusb and dmesg.log out put when I get home to give you more info.
thanks for any guidance you can give me,

Well, haven't got much further here unfortunately, though I have more logs and debug information now:
First, I connect the blackberry to the USB port and run 'lsusb':
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 002: ID 0fca:0004 Research In Motion, Ltd.
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
so I have my blackberry device listed by the looks of things..
I then run (for more info):

Maybe the blackberry required 'usb_modeswitch' - though I could not work out how to use this command
Any ideas out there? Is there a simple way for me to probe USB devices in use? As far as I can tell it IS /dev/tty2 but I need to confirm this.
Many thanks,

How to charge your Palm Centro via 64-bit Windows, with a USB cable

Here is a way to recharge your Palm Centro on your 64-bit Windows computer, through a USB cable. But first, a few brief explanatory notes...
Note 1: I have successfully used this method to charge my Palm Centro from my 64-bit Windows 7 computer. This method probably works for other Palm devices and other 64-bit Windows versions (XP and Vist)... but I haven't tested this on any other configurations. Others may feel free to post their successes or failures with their setups.
Note 2: This method will NOT allow you to HotSync your Palm to the computer via USB. All it does is let you charge your Palm via USB. If you need to HotSync your Palm, and you have 64-bit Windows, you have to use Bluetooth or some other method. To learn how to use Bluetooth to sync, search for "bluetooth sync 64-bit" or something like that on this forum.
Note 3: If you're wondering why someone would need to use this method - why not just plug the phone into a wall outlet, right? - it's because the Centro's charging jack can get messed up. Mine has not worked properly for the last several months
Note 4: I will not be posting any follow-ups to this message. This is my first (and only) post here... I'm posting here because I am very grateful to this forum: It is here that I learned how (and why) to sync my Centro to my computer via Bluetooth, because Palm doesn't support 64-bit Windows. This is my way of saying "thank you"! I'm not trying to be harsh by not following up... it's just that I won't be checking this thread, and I don't want anyone to have bad feelings if they ask questions and I don't respond. I'll be as thorough as I can in this one posting, though.
Note 5: I cannot claim credit for actually discovering this solution. I found it after HOURS of looking online... it was on some obscure website. Unfortunately, I can't remember where I found the original solution, so I can't credit the discoverer here. However, I have done my best to provide much more detailed instructions here.
Note 6: Lastly, Palm should support 64-bit Windows. Period. Some of you may say, "It's not Palm's fault - the company that makes the Palm OS is Access, and it's Access's fault for not supporting 64-bit Windows." Well, this may be true, but Access has stated that Palm has not requested a 64-bit driver. (In fact, you can call Access and ask them directly.) And if Palm doesn't ask (and pay) for it, Access sure isn't going to create one on its own. I used to LOVE Palm devices... I've used Palms for 12 years now, and for most of that time, I heartily recommended Palms to all my friends. But, between this problem and the other problems I've had with my current Centro and my previous Treo, I'm done with Palm. No more for me.
OK, here's how to charge your Palm (finally!)
1) If you haven't done so already, install the latest version of Palm Desktop / HotSync on your computer. You can get this at palm.com, under the "support" section. (Actually, I'm not sure if this is necessary, but I already had done this.)
2) As you're installing the software on your computer, toward the end of the process, do not actually sync your Palm to your computer. Just cancel or whatever you have to do to avoid that step. (Remember, the whole point here is that Palm does not have a driver compatible with 64-bit Windows, so you won't be able to sync via USB.)
3) If you don't already have it, get the PocketTunes application (also known as "pTunes") on your Palm device. If you have to install the software, you may need to do so wirelessly or via a 32-bit Windows computer (because, again, Palm doesn't support 64-bit Windows).
4) Connect the Palm USB cable to your computer. If you are using a desktop, plug into the USB ports on the BACK of your computer. These ports are directly powered, whereas the ports on the front of your desktop may not be. You'll want as much juice as possible to charge your Palm.
5) Connect the Palm USB cable to your Palm.
6) Turn on the Palm device, and open the PocketTunes application on your Palm.
7) PocketTunes will try to connect to Windows Media Player (on your desktop). Tell your desktop to connect to Windows Media Player. (You can save time by telling your desktop to do this automatically.) When PocketTunes connects with Windows Media Player, you'll have a power connection via USB.
8) PocketTunes will eventually show that it is "Idle" on the Palm.
9) To confirm whether the Palm is charging, look for the charging light (on the Centro, it's on the upper left) to turn solid red. You can also hit the home button on the Palm to see the battery / charging status. To get the charging working, you may have to exit PocketTunes and come back into it a few times before the charging light comes on. I have no idea why you have to do this; I just know what I wind up doing sometimes. You don't have to unplug and replug the phone from the USB cable, or turn the phone off and on. Just leave PocketTunes and come back to PocketTunes.
10) If you exit the PocketTunes application on the Palm, the Palm will still charge - but you'll get the constant and annoying "no driver" noise from Windows. To avoid that sound, just keep the Palm on PocketTunes while you have the Palm plugged into the USB cable.
11) You can close Windows Media Player on the desktop once you have the Palm charging.
12) Once you have this set up properly, you can speed up the process by setting the HotSync cable button to PocketTunes - after all, that button no longer needs to be set up to HotSync via USB cable.
When you have everything set up, here's what you would be doing on a regular basis:
-- Plug USB cable (which is already plugged into your computer) into Palm
-- Hit HotSync button on cable --> This starts PocketTunes --> PocketTunes automatically opens Windows Media Player on the computer
-- See if charging light turns solid red --> If not, exit PocketTunes, then hit HotSync button on cable to start PocketTunes again
-- Repeat until charging light turns solid red (success!)
-- Once the Palm is charging, close Windows Media Player on desktop
Best of luck to all who need this!

Why do you want to create your own driver instead of what comes with the device? If you go that route, you need all of the low level USB RAW protocol from the vendor. Did you get that? Yoe are wasting your time if you don't have that. Is the driver from the vendor documented? If it's a USB connection, how does that connection show up in windows device manager?
