USB device failures and need to re-update under Windows 7 / Satellite A505

I'm having a devil of a time trying to get access again to a set of devices which worked fine under Vista-32 and backward..
Recent self-repaired problem, The laptop refused to accept a Garmin eTrex GPS via any other USB port except port 1 (the top-left port).. Attempts to attach it via ports 2 or 3, resulted in failure to read device, and Windows Device Manager reported the GPS asn an unknown device. The fix to get it to accept the device on these ports, required uninstalling the driver to those two ports (plugging the device into either of those ports, when seen by Device manager, uninstall the device, unplug it, the plug it back in again.) result now, all 3 ports will now accept the gps.
Now, an old device failure.. I have 3 different Prolific USB to Serial (rs-232C) adaptor cords, for connecting to older serial devicees. (older GPS's, external older computers, robotics projects, etc.) as of yet, the above remove/replace method will not allow connection of these cables (yes, using the supplied drivers, and a few generic found online from Prolific themselves) and, likewise refuse to access the devices connected to them.
There is one other device, which uses another form of USB to serial (FTDI Chip, device is the Arduino microcontroller, which uses the FTDI D2xx chip to connect via USB) I'm surprised, is actualy in the installed Windows-7 driver library, as well as a Microchip PIC18C745 (Vellaman P8055 project board) (also native device under Windows-7)
I've tried to find a reliable Prolific driver, but as of yet, these devices (Including one used in Microsoft's labeled version of the Pharos GPS500 dongle, which is sold with Microsoft Streets & Trips 2009 (The driver for this one, on other computers has caused system crashes.. Even under Vista & XP)
Is this a problem with the laptop itself, or Windows-7 that I'm fighting?

You need to purchase a Mac OS X 10.6 DVD, which requires an Intel Mac with at least 1GB RAM. Run Software Update twice afterwards.
If you're already running Mac OS X 10.6, run Software Update until it gives you the option of installing iTunes 11.

How to increase the Speed of USB Devices (6501 and 6009)?

Hy guys!
My question is:
In datasheets of the USB devices, the only reference about the speed of
these boards is the Bus Interface speed (12Mbit/s). But in my
application (i'm trying to use delphi to control the device), each
instruction, doesn't matter if is a write or a read function, is taking
1ms to execute. Could i increase this speed?? What could be wrong?
OBS: I updated the Ni-DaqmxBase 1.4 to the new NI-DaqMx 7.5, and notting has changed.
Functions used:
istatus := DAQmxWriteDigitalU32(TaskEscrever, 1, 0, -1, DAQmx_Val_GroupByChannel, @writedata,nil, nil);
istatus := DAQmxReadDigitalU32(taskLer, -1, 10, DAQmx_Val_GroupByChannel, @readdata[j], 1,nil, nil);

Hello,
The two usb DAQ from NI are full speed interface (as you said 12M/s bus speed). The full speed interface has a frame size of 1ms, the root hub transmits a packet every 1.0 ms and this is the minimum time that you can read/write from/to usb device, normally because of the windows scheduling, 1ms is very tight, windows may miss it in some occasions, some usb device designers would prefer to use something between 2ms - 10ms polling period, which means some devices may even react to commands within 2ms - 10ms. But it looks like the two NI usb DAQ use the 1ms polling period and that is the shortest time you can get in software paced mode. If you need very fast digital update rate, you may need to look at PWM output, it generates digital pulses at very fast rate as the link given below, the iUSBDAQ - U120816 can generate PWM pulse from 3kHZ - 333kHZ.
NI USB DAQ maybe good, but it wouldn't hurt to look at some other company's product too. the below link of usb daq gives the best price/performance ratio, LabVIEW vis are very easy to use and you avoid the pre-configuration in a separate application for DAQs which sometimes may be big deal if your customers are not engineer or scientist, but regular computer users. You are welcome to compare.

PTCL EVO USB Device Installation and Configuration (EVDO CARD)

*PTCL EVO Installation on MAC Book PRO , Mac Book Air EVO*
Problem:
USB not getting detected on MAC book pro and Mac book Air.
Resolution:
*DO not Insert the EVO CARD until you perform the below:*
*Getting the driver:*
*Option 1 :*
http://ptcl.com.pk/contentb.php?NID=327#drivers
Select the device you have and download MAC driver from the download section on the page.
*Driver Option 2:*
ON windows os insert the EVO device detect the USB disk with drivers one of the driver is for MAC (dmg file) copy it on a simple Flash disk.
*Installation on MAC:*
Double click the downloaded driver (Option 1)
run the setup.
or
on your MAC Insert the Flash Disc on which you copied the driver (Option 2) it will detect a media storage and then run the driver from there. Once you have the driver installed you will see an EVDO Icon in the menu.
*NOW insert the EVDO USB in MAC it will be detected as a modem / network device.*
*TRICKY PART:*
EVO software does not work on MAC so you need to configure a manual connection.
Go to network settings from the top panel under WIFI click advance settings. A new menu opens up you will see 3 or 4 new devices. you need to configure the EVDO Card Terminal only thats the first in the list.
*Do not configure any other device.*
*Config Settings:*
phone number: #777
User: [email protected]
Password: ptcl
*Do not change any other settings.*
Click connect and within seconds it will connect.
It works fast and reliable for all wimax services location is very important it is dependent on the signal strength. EVO is the best choice for people on the go as it works across Pakistan in 350 cities. no other service can match this.
Please note I am not from PTCL or any affiliation with them. Check my website for more details…

Hey Mark
You didn't happen to change the IOMMU setting in the UEFI did you? I have just got a M5A97 EVO and been having problems.
This UEFI interface finds the usb devices fine but the kernel will not. I found that if I flash the bios it reset things and appears to
just compare the flash if it is the same. Afterwards the usb works. However I still trying to narrow it down myself. I've tested with
0402 0810 & 0813 just released. All do the same thing with regards to usb 2.0.
Jonathan
EDIT:
After testing it appears to be connected to the linux nvidia blob & IOMMU settings conflicting.

Mountain lion USB devices issues and Cam

Hey Guys,
Since updated to ML, started having an issues with many USB devices, (Apple wire Keyboard, Razer Deathadder mouse, iPhone, NI Maschine, Guitar Rig Mobile), basically everything that is connected over USB bus. As well as Web cam, not sure how its connected internally but looks like over USB as well. Mentioned above devices sporadically getting hanged and becoming not available and I have to reboot the whole iMac (this is insane!!!). My is iMac 27-inch, Mid 2010 (3.2 x2 cores, 8GB of RAM). In general, system super slow, Terminal is lagging when openning (its simple Bash, changed to zsh by default, much better), didn't had such issues on Lion nor on Snow Leo.
Please help! what can be done to fix this? Should I roll back to Lion? When will be an update for those type of lags? this is epic fail.
Best regards,

Another iTunes 11 crash. Something as simple as downloading one new app to the iPod Touch 5.
Memory seems to really climb when searching iTunes store.

USB Device Not Recognized - Caused by iTunes Update???

I have been reviewing the posts associated with USB Device Not Recognized and many persons have had this problem, but most are within the past 10-12 days. My problem started after installing an iTunes update.
Can Apple please advise if the latest iTunes update interacts with Windows to cause this problem (which remains even after iTunes is uninstalled).

Check if any of the tips in this thread can help you.

Envy Touchsmart 15-j105sa Continuous USB Device Dropout and Reconnect

New Envy Touchsmart 15-j105sa running an up to date version of Windows 8.1. All HP driver and Windows updates completed prior to installing software and other USB devices except for USB WiFi adaptor and software.
USB 2.0 HDD keeps disconnecting from the port and then re-connecting. This happens continuously about once every 30sec. It re-connects after about 10sec and then disconnects again after about 30sec. When connected everything seems to be working fine. Access to the HDD is OK, it shows normally in Device Manager and Safe Disconnect.
I have uninstalled the USB drivers and restarted. The problem persists. I have powered the USB HDD externally. The problem persists. I have tried connecting to 3 of the 4 USB ports. The problem persists. The USB 2.0 HDD works normally on other Laptops. When data is being transferred the dropout does not occur. It appears to be associated with idle time on the USB HDD.
I don't get the problem when I attach a USB 3.0 HDD. It stays connected with no dropout. Flash drives don't have the problem.
I also have a similar issue connecting a USB Alfa WiFi Adaptor.
UPDATE: The problem is related to an External Combo Drive. 2.5" Sata to USB /eSata HDD External Enclosure. As long as the HDD is being accessed then there is no dropout. As soon as the disc becomes idle I get a cycle of disconnects and reconnects as described above. I would like to understand the cause of this issue because it will help solve the massive connect/disconnect hunting that I get with my external USB wifi adaptor. Once the Alfa Wifi adaptor gets happy with its connection the hunting stops and it behaves normally.

Are you using the charging USB 3.0 ports or the standard USB 3.0 port to connect the device?
Charging ports have a + next to them. It really should not make a difference, but it might with your keyboard since it does require more power then, perhaps a mouse.

Hi! Why is it that after I updated thru the app center my OS X 10.9 to 10.9.2 (Combined), after it downloaded and restarts, this error occurs, "the version downloaded is corrupted and needs to download again."? I have been repeating the process for more than three times already but the same problem keeps on happening. Please advise.

Try the manual update:

USB devices disapear and only reappear after a full power down

Hi All
Has anyone seen this before, The USB devices (Mouse/Kboard/ilok) started to be flaky and then disappeared. After a soft restart the Mouse and keyboard came back but not the Ilok. After a hard reset eg pulling power for 30sec everything has come back. Is this a sign of things to come, power supply issues etc?
Thank you
Mal

In some cases, the keyboard plus mouse is right at the edge of acceptable power draw, and adding anything to the second keyboard outlet causes it to malfunction or over-power and drop out.
The Mac Pro has separate power budgets for the front ports in total and the back ports in total, so one approach might be to plug in the other stuff on the other side.

For those who run Windows 8 with bootcamp: Do you update windows 8, with windows update? I have the latest bootcamp drivers, and never checked for updates on windows. Do you normally update windows 8?

Windows 8 has been running very well after installing it with bootcamp and its latest drivers.
I just have never updated Windows 8 itself, (windows has never checked for updates), and just has been
using it bare. Do you update windows 8 to the latest updates with windows 8, and have any problems
with the updates? Just curious before I start updating it for once.

You have to update Windows to the latest version with Windows Update and keep it updated, because this is a matter of security. Microsoft provides a lot of security updates and you have to install them even if you have got an antivirus. Then you can find other updates, and if you want to install Windows 8.1, just install all updates with Windows Update, and then go to the Windows Store and download Windows 8.1.
Apple says that Windows 8.1 is not supported by Boot Camp, but people say it works without any problem with the most recent drivers, so I do not find any risk after upgrading to Windows 8.1.

Adobe Acrobat Prof. 8 and Adobe Reader Version 11 under Windows 8.1 x64

Good Afternoon,
my company plan migration from Windows XP to Windows 8.1 x64. For this reason shall I find out, which Software run under Windows 8.1 x64. From Adobe Products we need to know, if Adobe Acrobat Prof. 8 and Adobe Reader Version 11 run under Windows 8.1.
If the Software named above run not under Windows 8.1 x64, could you write me please, which version we need und how much it is. Thank you very much.
Best Regards

If you have Acrobat, there is no need for Reader. Acrobat 8 is not certified for use on Win8.1, only Acrobat XI. You can get the current cost from the Adobe Store at Adobe.com. The cost is a per computer license. If you have a lot of computer, you might be able to negotiate with Adobe on a volume order or site license (for so many licenses) -- you would have to call Adobe on that.
AA 8 can be made to work in some cases, but I would not recommend it in a business environment. It is not worth risking some hickup with software that is marginally compatible when you have some deadline or such.

Mac-formatted ipod software updated under windows - all files vanished

Hi.
I just accidentally upadted my iPod Software under windows, but I have a Mac-formatted iPod. Now I can't find any of my files anymore., even though the ipod is still filled with 27 GB of data. Is there any way to reverse this and get my files back or do I have to restore the ipod and thus erase everything? any suggestions would be appreciated...
cheers,
Colt

Hello all, I figured I'd join in.....sorry, no help here, I am also looking for an answer. I too have a 5G 60GB and it was formatted for Mac, I tried accessing it through xplay2 in Itunes and accidently updated it (Windows XP.) Now it just runs in a continuous loop of rebooting itself, most likely until the battery dies???....doesn't look good for the home team... any beta would be appreciated.
thanx dr
