Mac usb tastatur funktioniert nicht

Auf dem Air gab es keine Probleme! Es muss sich um einen Hardwaredefekt handeln, da dieses Probleme auch bei einem frisch installierten OS auftraten. Ah, dann hatte ich das falsch verstanden, sorry.

Ich bin immer noch entschlossen zum Service zu gehen, mache gerade noch mal frische Backups, glaube aber nicht das ich 2 Tage vor Weihnachten noch da hin komme Aber nur mal theoretisch: Die Probleme traten erst mit Update auf Sierra auf. Marcel Bresink Zehendlieber. Am Besten in einem Apple Store. Nachdem E muss etwas mit dem Kartenleser zu tun haben. Allerdings war man bei mir in diesem Fall nicht ganz sicher. Im Apple Store in Berlin hat man wohl versucht, so alles zu wechseln was nur geht.

Ohne Erfolg.

Das hat 14 Tage gedauert. Eine Woche dann weiter hatte ich einen neuen Mac, da die weitere Suche und der Aufwand nicht in Relation steht. Gestern war es nun wieder so weit! Wollte meinen Mac hochfahren und hatte Probleme bei der Anmeldung. Danach keine Probleme mehr! Somit sieht es so aus, als ob der SD Kartenleser an diesem Problem beteiligt ist! Ein grundlegender Fehler kann es ja wohl nicht sein ich habe auch ein Macbook und da klappt Filevault ohne Probleme und das zweimal der Kartenleser defekt ist, ist doch eher unwahrscheinlich.

Es hat nichts mit der SD Card oder Fifty zu tun! Ignorierte Inhalte anzeigen. Benutzername oder E-Mail-Adresse: Besitzt du schon ein Benutzerkonto? Nein, erstelle jetzt ein Benutzerkonto.

Disable wireless networking devices: Change Power Options: Change the Power Options on your computer PC's only. Change power schemes to "Always On". Also change all of the Always On Power Scheme settings to "never".

Set your Line 6 device as the main sound card on your system: See these Knowledge Base items to learn how: These cards often solve the problem of white noise, communication issues and other problems because the USB implementation on these cards overrides the many times less robust USB bus built into your computer. For more information on PCI Cards please visit.

For more optimization tips, see Computer System Audio Optimization knowledge base article. Chipset Error Explanation: If the computer fails to meet standard USB requirements, a possible result the soundcard creates a "white noise burst" at the analog audio outputs.

The chipsets we have verified as having this problem are the G, P and X chipsets, although others may be affected as well. Intel publishes on their web site an Errata that provides a more detailed explanation. Please note that computers that create this problem produce issues with all USB 1. For instance, Digidesign provides their customers with similar information on this Intel chipset problem.

Also note that your computer may have this problem even if other USB devices seem to behave normally. This is because other USB devices like USB printers and hard drives generally use USB's bulk mode of transfer, and do not produce noticeable problems if data is momentarily interrupted, as on these problem Intel chipsets. USB 1. These Intel chipsets fail to consistently provide the continuous data flow required for the isochronous mode and audio. If you want to know if your chipset is one of the affected ones, go to this link and download the program CPU-Z 1.

This program will gather detailed info on your CPU. Once downloaded, run the program, select the "Mainboard" tab and note the information where it says "Chipset" e. We do not have a solution that ensures proper performance on these computers. Once these cards are installed, these computers often stop exhibiting the "white noise burst" problem, because the USB implementation on these cards overrides the flawed built-in USB implementation of the computers.

ISA motherboards operate at lower bus speeds, and can slow down your computer and can sometimes cause "clicks" in the audio. We recommend using a non-ISA board. Line 6 cannot support the use of powered USB hubs as they can cause connection issues with our server through our software such as Line 6 Monkey or License Manager. Powered hubs can also create connection issues between our devices and our drivers.

However, there have been a few cases where powered hubs actually resolve pops and clicks on certain laptops where the USB ports may not be providing enough power to the Line 6 audio interface.

Remove all unused USB drivers: It can be downloaded at: Advanced Troubleshooting: We have seen these techniques work for other users who are experienced with advanced computer adjustments. Perform these advanced procedures at your own risk. In some cases, the ultimate resolution was to replace the computer. Speedstep is an Intel efficiency tool that enables the CPU to speed up and slow down according to the load put on it.

However it also changes the voltages running through the CPU accordingly and may cause crackles when the CPU steps up and down. C1E is the auto voltage setting that is usually enabled along with Speedstep. This should set the CPU to run at its fixed maximum speed with no voltage changes. Troubleshooting involves disabling hardware one item at a time, then running the Latency Checker each time until the latency subsides in the checker. Replendence LatencyMon: LatencyMon http: It will provide a comprehensible report and find the kernel modules and processes responsible for causing audio latencies which result in drop outs.

Be sure to read some of the possible root causes for pops and clicks that the developer of this software offers up under the description of this tool. Some of these advanced tips may help you resolve your issue. OS Reinstall: Complete fresh install of your Operating System in the event certain essential OS files or settings have gone bad. Hard Drive Reformat: Reformat the hard drive to clean out the registry and remove any problem-causing files. Reinstalling the OS and other applications after a reformat of hard drive may repair previously unfixable problems, and may improve system performance.

Generally, if you have an IRQ problem, increasing buffer sizes should fix it or at least improve it.

If the problem has something to do with USB bus corruption, or a problem with power, then increasing the buffer sizes wouldn't change anything. We recommend that you consult with a qualified computer technician to verify if this is the case. Be advised that most technicians aren't properly equipped to deal with such an in-depth technical issue. They may suggest replacing the motherboard, but that may not fix it unless the replacement is a known working model.

This is because the problems stem from design issues on the motherboard and will be common to all motherboards of that revision and model. USB Audio: Optimieren Sie Ihren Computer zur Audionutzung.
